The structure of the Mitsubishi Lancer engine 9 automatic. mitsubishi lancer sedan

Mitsubishi Lancer 9 in-line four-cylinder engines with a volume of 1.3 and 1.6 with one camshaft and a power of 82 hp. and 92 hp respectively; 2.0 with two camshafts and a power of 135 hp. when operating in the conditions of the Russian Federation, they have a small resource and high oil consumption.

The oil consumption on the Lancer 9 is so high that when the next scheduled maintenance is reached, you can only replace the oil filter. After all, consumption, or rather "zhor" oil varies from 1 liter to 3 liters per 1000 km. With an oil system volume of 3 to 4 liters, for 10-15 thousand km. you will have to add at least 15 liters, and thus change it several times.

In the absence of leakage of oil seals, gaskets and seals, the reasons for oil consumption can be:

• Wear of valve guides and seals
• Wear or coking of oil scraper rings, scuffing on the cylinder block

Every cause has its own root cause.

Oil flow through valve seals

Valve seals lose their elasticity and “tan” at different mileage. On one engine, they are replaced at 50 thousand km. run, on the other 150 thousand km. At the same time, at a higher mileage, replacing the oil seals does not solve the problem with oil consumption. Why is that? Valve stem seals fail due to overheating, both visible, when the temperature sensor detects it, and invisible, the so-called internal preheating. In the first case, the cooling system may be the cause. The second case is difficult to diagnose and detect, and it is associated with poor fuel quality. The products of incomplete combustion of gasoline form soot and varnish deposits in the combustion chamber. As a result, the thermal conductivity of its walls deteriorates, which causes overheating, which is not detected by the temperature sensor. In addition, self-replacement of valve stem seals without troubleshooting and subsequent replacement of valve guides does not give a positive effect. And Lancer, as he ate butter, so be it. And, if we take into account the pumping effect that occurs when installing new seals on old bushings that have wear, then the flow rate will be even greater than before replacement.

Occurrence of rings and oil consumption

Oil scraper rings in case of overheating of the Lancer motor lie down and lose their mobility - this is one of the reasons for oil consumption. When using poor quality gasoline, the rings coke and also stop working. In addition, if the coke clogged the grooves and the rings lay on it, then their intensive wear against the cylinder walls will occur. As a result of mechanical wear, scoring can occur on the sleeve, which is another reason for oil consumption. The compression rings also cause a pumping effect when the oil scrapers are stuck and the flow will rise. Replacing the rings does not work if the cylinder block is not bored to a new size or the surface is not micro-polished. Wear in the block leads to a change in the geometry of the cylinder: ovality, taper, ellipse, which in turn causes the engine to knock. The knock can also be "rod" due to oil starvation.

The root cause of the "zhora" of oil on Lancer 9

What does the fight for the environment and the reduction of toxic emissions lead to? It is necessary to optimize the clearances in the motor and its parts. The smaller the gaps, the easier and faster they are clogged with products of incomplete combustion of gasoline. It is for this reason that all of the above happens, and that is why all manufacturers write and warn about the use of high quality fuel. Exacerbates the situation and objective reasons:

• Short trips
• Driving an unheated car
• Continuous idling
• Use of gasoline that does not comply with the passport
• Operation at low speeds

These factors do not allow the engine to reach the operating temperature at which coke and carbon deposits will be burned out. The use of AI-98, instead of AI-92, also contributes to carbon formation, since the burning rate of high-octane gasoline is lower. What does not burn forms soot, clogs the catalyst.

How to increase the life of a Mitsubishi engine

Increasing viscosity and switching to other brands of engine oil do not give a sustainable result. Regular use of flushing the oil system before changing the oil - MF5 will keep the power unit clean. Flushing the Lancer motor allows you to deeply clean the surfaces of all types of deposits and soot, decoke the rings and restore their mobility.

The use of a ceramic-metal additive for the engine will restore its resource, compensate and protect it from wear. The composition of Engine GA4, designed for 4 liters of oil, does not change the chemical composition and physical properties of the oil. It forms a ceramic-metal protective layer on mated friction pairs, which restores the geometry of the cylinder, increases compression, as a result of which Lancer 9 oil consumption decreases or even stops, depending on the degree of wear and the causes of "zhor". The composition does not affect and does not restore valve seals, piston rings.

It is possible to optimize combustion processes and get rid of the consequences of incomplete combustion of fuel with the help of an additive in gasoline combustion catalyst, FueleX. The combustion catalyst increases the rate and temperature of combustion, resulting in complete combustion. And as a result, there is no soot, coke and deposits - a clean engine, combustion chamber, catalyst. The use of a combustion catalyst increases the life of the motor.

Mitsubishi Lancer 9 sedan - body specifications

The four-door, three-volume Mitsubishi Lancer IX sedan belongs to class C cars. The special attention of the creators of the Mitsubishi Lancer 9 to the safety characteristics of the body is not accidental. At one time (1998), sales of the Lancer in Europe failed precisely because of the low safety of the body. Thank God, the Japanese came to their senses in time, and by the time the Lancer IX was released, this shortcoming was completely eliminated. The car body cage is endowed with a rigid frame, with additional ribs installed on the sides and in the doors. Also in the body structure there are components and parts with a pre-programmed distribution of the force load in collisions and collapsible elements. Body warranty against through corrosion -12 years.

4G15 - 92-horsepower engine with a displacement of 1.5 liters. It consumes an average of 6.3 liters of fuel per 100 kilometers. It was not supplied to the Russian market. Works with both a 5-speed manual transmission and a 4-position automatic.

4G18 - four-cylinder 98-horsepower engine with a volume of 1.6 liters. According to statistics, this is the most popular engine for Mitsubishi Lancer 9 sold in the Russian Federation. The average fuel consumption per 100 kilometers is 6.7 liters. Adapted to work with a 5-speed manual transmission and a 4-position automatic transmission.

All Mitsubishi Orion engines used in the Lancer 9 sedan trim levels are built according to the SONC scheme (single camshaft). Toxicity standards are Euro 4. In the Russian market, the version of the Mitsubishi Lancer sedan 9 automatic with a 4G18 engine after 2005 was also equipped with a 6-band transmission of the INVECS III CVT type (600 copies sold).

The 4G6 series motors belong to the Mitsubishi Sirius family. These include:

4G63 - four-cylinder, 135-horsepower engine with a volume of 2.0 liters, with two camshafts (DONC). The average fuel consumption per 100 kilometers is 7.6 liters. It was presented on the Russian market only with a 5-speed manual transmission.

4G69 - SONC engine with a volume of 2.4 liters and a power of 162 horsepower. This motor was created specifically for the American market and only for the Lancer 9 automatic version (Ralliart) with a 6-band automatic transmission as a transmission. Average fuel consumption - 8.8 liters / 100 km.

A series of 4G9 engines created using MIVEC technology, which provides electronic synchronization of cylinder operation in 2 different modes - separately at low and high speeds - is represented by the 4G93GDITurbo engine. This 160-horsepower power unit with a volume of 1.8 liters is able to accelerate the sedan to a speed of 100 km / h in 8.9 seconds. At the same time, the average fuel consumption is 6.6 liters / 100 km. Unfortunately, the Lancer IX sedan with this engine was not officially delivered to Russia.

Sedan Mitsubishi Lancer 9 - chassis characteristics:

Front suspension - independent MacPherson struts;

Rear suspension - independent "multi-link" + anti-roll bar;

Steering - rack and pinion type with hydraulic booster;

Brake system - disc with anti-lock ABS.

Modern Japanese Mitsubishi Lancer 9 cars are equipped with internal combustion engines of various sizes. The volumes are equal - 1.3; 1.6 and 2.0 liters. Four-cylinder injection gasoline engines have a transverse arrangement.

Engines with a smaller displacement are equipped with a SONC type gas distribution system (with one camshaft), and a larger engine on the Lancer 9 is equipped with DOHC (with two shafts), respectively.

Design features of Mitsubishi Lancer 9 engines

Cooling of vertical cylinders - liquid. Four valves open and close under control of camshafts.

The Mitsubishi Lancer 9 DOHC two-liter engine develops 135 horsepower, and smaller SONC-92 and 82 hp engines. With. respectively.

The material for the manufacture of the cylinder head (cylinder head) is an alloy of light metals.

Pros and cons of the ninth motor

One of the main advantages of Lancer 9 motors include the following indicators:

1. High economy.
2. Good traction properties.
3. Quick easy cold start at any ambient temperature.

Thanks to these qualities, the Lancer 9 engine is in great demand in countries with harsh climates.

The main disadvantage: high sensitivity to the quality of fuel and road surface. Many defects appear due to untimely or poor maintenance.

Engine maintenance and repair

The complexity of repairing power units of the Mitsubishi LancerIX model depends on the frequency of preventive measures. Car owners should regularly change engine oil, clean fuel and air filters.

Mandatory preventive measures also include regular checking and changing the timing belt (gas distribution mechanism). The frequency of the operation depends on the following factors:

• road quality;
• climatic and weather conditions;
• driver's driving style.

The efficiency of power units is ensured in the complete absence of defects. If the engine has a breakdown in the cylinder-piston group, gasoline consumption increases significantly. To solve the problem that has arisen, a complete replacement of all elements included in this group is required.

Repair procedure:

1. Switch off the electrical circuit.
2. Remove candles.
3. Disconnect the output manifold.
4. Dismantle attachments.
5. Remove the cylinder head cover (cylinder head).
6. Remove the timing belt.
7. Remove and clean the oil pan.
8. Loosen the connecting rods.
9. Take out the pistons.
10. Remove the rings and clean them from soot layers.
11. Disassemble the cylinder head.
12. Remove crackers and caps.
13. Clean and flush the cylinder head.
14. Rub the valves.
15. Reassembly.

If it is necessary to replace some elements of the engine, it is recommended to use original spare parts.

The choice of lubricant for the Lancer 9 engine

Many car owners are interested in which oil to pour into the Mitsubishi Lancer 9 engine. The choice of engine oil must be made in accordance with the recommendations of the automaker according to the CAE viscosity and temperature table. The most common brands of lubricant are: 5W-40, 5W30, 0W-40, 0W-30.

With a complete oil change, experienced motorists and car service masters advise changing the oil filter at the same time. The recommended time interval between complete oil changes is indicated in the vehicle passport.

It is useful for an engine operating in difficult and dusty conditions to change the oil after 10 thousand km.

The engine on the Mitsubishi Lancer 9 is distinguished by its original structure and design features. They equip a Japanese car with three types of internal combustion engines: 1.3, 1.6 and 2. Over time, it becomes necessary to repair the power unit.

Let's consider the car's engines in more detail, which will make it easier to carry out repairs on the Mitsubishi Lancer 9 if necessary. The location of the internal combustion engine on the machine is transverse. All engines are "four", and the car is equipped with injection gasoline units. The difference between them is only in the difference in working volume and design features. So, both “weak” motors are of the SONC type, and the 2-liter unit is of the DOHC type.

Note. The difference between SONC and DOHC is in the number of camshafts. DOHC has two.

The cylinders in the Lancer 9 engines are located vertically and are liquid-cooled. Two engines with a small volume and a third with a high one have the same four-valve structure. The valves are actuated by the camshaft. The rotational energy is transferred to the rocker arms (for SONC) or push levers (for DOHC).

SONC motors develop 82 and 92 hp. respectively, and the 2-liter DOHC engine - 135 hp. The cylinder heads of the Lancer 9 engines are made of an alloy of light metals, the purge scheme is carried out by means of the opposite arrangement of the intake and exhaust channels.

Advantages and disadvantages

Most experts called the advantages of Mitsubishi Lancer 9 power units high efficiency (although this does not apply to used Lancer 9), and, of course, excellent traction characteristics. And thanks to its easy start at any temperature, Lancer 9 is in demand in countries with cold climates, including Russia.

Among the disadvantages of internal combustion engines, high sensitivity to low-quality fuel and off-road can be distinguished. Distribution also received those defects that arise due to poor-quality or untimely maintenance.

Repair

Repair of the Lancer 9 power unit is the more difficult the longer preventive procedures have not been carried out. Owners should timely change the oil, clean the air and fuel filters.

Engines of the 9th generation of Lancers are economical, but in practice, used models show too much fuel consumption, especially if there are any defects. And only a complete replacement of the piston group helps to solve the problem.

The timing belt, along with the roller, needs to be replaced regularly, after a certain period of time (specifically, it depends on climatic conditions, road quality and the driver's driving style).

The Lancer 9 internal combustion engine repair algorithm is as follows:

• bobbin and armored wires are dismantled;
• candles are removed;
• the output manifold is disconnected;
• all attachments connected to the cylinder head cover are dismantled, including sensor connectors;
• the cylinder head cover is removed;
• the timing belt is dismantled;
• the oil pan, unscrewed from the bolts, is dismantled and thoroughly cleaned;
• the pistons are removed after preliminary loosening of the connecting rod clamps;
• rings are removed;
• carbon deposits remaining on the pistons are thoroughly cleaned;
• the channels through which the lubricant is discharged are also thoroughly cleaned;
• the cylinder head is disassembled;
• crackers are taken out;
• caps are removed;
• The cylinder head is cleaned and washed, then purged;
• the lapping process is carried out on the valves;
• assembly is in progress.

The diameter of the caps on the power unit of the lancer should be 9 mm. In this case, you can use both parts of the original production, and duplicates.

Timely protection of the internal combustion engine, preventive measures and care will make it possible to extend the life of the car. You can learn more about how engine repairs are carried out on Lancer 9 from other articles on our site (in particular, about).
