The Mercedes-Benz 112 engine is hard to go uphill like the sound of a diesel engine

When accelerating, when driving, you may not be able to hear it. It may be caused by the cylinder valve, and the adjustment of the valve can be changed. Lack of oil, lack of oil may also cause similar problems. In addition, the oil pressure is relatively low, so the engine oil pressure must be checked.

The engine accumulates carbon. Long-term insufficient combustion causes the carbon component in gasoline to be left inside the engine, resulting in carbon accumulation. If there is too much carbon accumulation, the engine will have jitter, abnormal noise and other problems. At this time, fuel additives should be used to clean up carbon. Oil line failure.

When the engine is idling, it makes a clicking sound, as if something is hitting the metal. When accelerating and driving, you may not be able to hear, which may be caused by the cylinder valve. The adjustment of the valve can be changed.

Is Mercedes-Benz engine 272 and Mercedes-Benz 112 engine common

The number of cylinders between the two is different. The Mercedes-Benz 112 engine is a relatively old 6-cylinder engine, which has been replaced by the 272 engine. The 112 engine is used in older models, such as the S280 of the 220 chassis, the E-class car of the 211 chassis, etc. The Mercedes-Benz 113 engine is a V-type naturally aspirated 8-cylinder engine, which is generally equipped in off-road vehicles or performance vehicles.

Generally speaking, the horsepower of the car engine is large and the torque is also large. If torque is used to represent power, it can be written as a formula: N=Mw, M is the torque, and w is the angular velocity of rotation.That is to say, we just said that the torque and horsepower are also large, the premise is that the rotation speed is the same.

The types are similar, and they are adjusted for different models! 104 119 /111 112 113 137/271 272 273 27 Now these are the mainstream engines running on the road of China! L4, L6, V6, V8 and V12 S500 do not have turbochargers.

Mercedes-Benz 112 engine parameters

1. The Mercedes-Benz 112 engine spark plug model is 12*IFR6Q-G. The M112 engine adopts a double spark plug ignition system, and the phase is transferred to double spark plug ignition, and each cylinder has 2 spark plugs. The cylinder diameter of the 2L6-cylinder engine and the 3L8-cylinder engine is 89mm, and the stroke is 84mm.

2. Different displacement and different time. The displacement is different. The displacement of Mercedes-Benz engine 272 is 8t, while the displacement of Mercedes-Benz engine 112 is 0t. The time is different. Mercedes-Benz Engine 272 is developed from Mercedes-Benz Engine 112. The release time of Mercedes-Benz Engine 272 is later than that of Mercedes-Benz Engine 112.

3. According to the information released by the official website of Mercedes-Benz Automobile, the Mercedes-Benz engine 272 is a V-type 6-cylinder engine with a displacement of 8t, while the Mercedes-Benz engine 112 has a displacement of 0t. The displacement of the two engines is different, and the exchange of use will cause internal damage to the car and cannot be used.

4. Mercedes-Benz (imported) production status: manufacturer's guide price: 8.98 million dealer quotation: 8.98 million engine: 0 L6 313 horsepower gearbox: 9-speed manual automatic basic information origin attribute: imported grade.

5. The number of cylinders between the two is different. The Mercedes-Benz 112 engine is a relatively old 6-cylinder engine, which has been replaced by the 272 engine. The 112 engine is used in older models, such as the S280 of the 220 chassis, the E-class car of the 211 chassis, etc.

Mercedes-Benz 112 engine idling speed is high

ignition system failure. The idling jump may be due to the failure of the ignition system, such as the damage of the spark plug, which needs to be replaced. In addition, there may be a problem with the high-voltage wire and ignition coil, which can be judged by the car computer and then repaired specifically. The oil pressure is abnormal.

The high idling speed of the car is usually caused by the following reasons: low engine water temperature, turning on the air conditioner, engine powerWhen the pressure is low, the ECU program design should appropriately increase the idling speed. This is a normal situation. If the engine water temperature is normal, the air conditioner is not turned on and the idling speed is high, it means that the system is faulty, which may be an electronic control system or a mechanical system failure.

Under this normal situation, if the engine water temperature is normal, the idle speed is high and there is no on-air adjustment, it means that there is a problem with the system, either the electronic control system or the mechanical system. When encountering mechanical failures causing high idling speed, focus on checking whether the intake pipe is leaking, the vacuum tube is falling off, damaged, and the intake pipe is damaged (the intake pipe of the Volkswagen engine is mostly rubber tube).

Generally speaking, the main reason for excessive idling is excessive air intake or the engine control signal error when idling.

The main reasons for excessive idling speed are as follows: the idling switch is not closed;The idling control valve is faulty; the intake pipe is leaking; the gas distribution phase is wrong; the fuel injector is dripping or blocked; the exhaust system is blocked; the EGR valve is open during idling conditions.

If the idle speed is high under normal circumstances (the engine water temperature is normal and the air conditioner is not turned on), it may be a system failure, such as an electronic control system failure or a mechanical system failure. Mechanical failures that cause high idling speed need to detect the leakage of the intake pipe or the fall and damage of the vacuum tube (the intake manifolds of the Volkswagen engine are mostly rubber tubes).

The difference between Mercedes-Benz engine 272 and Mercedes-Benz 112 engine

According to the information released by the official website of Mercedes-Benz Automobile, the Mercedes-Benz engine 272 is a V-type 6-cylinder engine with a displacement of 8t, and Mercedes-Benz startsThe displacement of the machine 112 is 0t. The displacement of the two engines is different. Exchanged use will cause internal damage to the car and cannot be used universally.

If the torque is inversely proportional to the speed under the same horsepower, the torque of the engine with high speed will be smaller. In a car, torque = power/tire speed/3. 14159/2=Grith * Tire radius.

The number of cylinders between the two is different. The Mercedes-Benz 112 engine is a relatively old 6-cylinder engine, which has been replaced by the 272 engine. The 112 engine is used in older models, such as the S280 of the 220 chassis, the E-class car of the 211 chassis, etc. The Mercedes-Benz 113 engine is a V-type naturally aspirated 8-cylinder engine, which is generally equipped in off-road vehicles or performance vehicles.
