Insufficient engine power refers to the poor power performance of the engine, and there are many reasons for failure.
1) The general cause of the failure.
The high-pressure spark is too weak or the ignition is not on time. The main reasons are that the high-voltage line jumpover is too weak, the spark of the high-voltage distribution line is too weak, the ignition coil or igniter works poorly, and the ignition advance angle is too large and too small.
The combustible mixture does not meet the requirements. It includes that the combustible mixture is too thin and too thick, the injector atomization is poor, the amount of combustible mixture entering the cylinder is not, and the combustible mixture burns abnormally.
Insufficient cylinder pressure.
Vacuum pipe leakage.
The exhaust pipe is blocked.
The distribution phase is abnormal.
The mechanical loss of the engine itself is excessive. For example, the piston and cylinder fit too tightly, the crankcase oil is too thick, the intake valve is carbon deposited, air leakage, etc.
The exhaust gas recirculation valve does not close or does not work properly.
2) The reason for the electronic control system.
The throttle position sensor is faulty. For example, the throttle is too dirty, the sensitivity decreases, and the response is sluggish.
The air flow sensor is faulty. If the test data is inaccurate or there is fouling on the air flow meter**.
The coolant temperature sensor is faulty. If the temperature of the coolant is not reflected correctly, an error signal is provided.
The intake manifold pressure sensor is faulty. If the signal cannot be output, the computer will keep the engine running according to the pre-set signal, but the pre-set signal cannot be adjusted with the change of vacuum level, resulting in the deterioration of engine performance.
The crankshaft position sensor and camshaft position sensor are faulty. If the speed signal cannot be transmitted correctly, the engine ignition will not be correct.
The Hall sensor is faulty. If the electronic control unit is not working well, causing the fuel injection time to be too long, after the oxygen sensor detects it, the electronic control unit will reduce the pulse width of the fuel injection, so that the mixture will become thinner, resulting in poor engine work.
Poor line contact. For example, the injector harness side connector terminal contact is poor and the tie wire contact is poor.

Anonymous users2024-02-09Summary. Dear, the maximum speed of the 340 engine is 2400 rpm Oh What controls the engine speed of the Weichai 340.
Dear, glad to answer for you! <>
The engine speed of the Weichai 340 is controlled by the electronic control module of Xunjian in the engine control system. The electronic control module receives the speed, load and temperature of the engine through the sensor, and then controls the speed of the engine according to the program, the amount of fuel injection, the amount of air intake, and the ignition timing to control the speed of the engine<>
Kiss, give you an extension <>
ECM can be done according to the operation and the driving state of the vehicle, adjust the speed of the engine, can achieve good fuel economy and power energy, it should be noted that the slippery nonsense, ECM is the engine control system in the xing energy and stability xing has an impact on the operation of the engine, it is necessary to avoid being trusted to encounter damage oh <>
We are direct injection machine.
Dear, the direct injection machine is also controlled by an electronic control module.
Where is the electronic control of this direct injection machine?
Dear, the electronic control module of the Weichai 340 engine of the direct injection machine is located on the top and side of the engine
What is the engine speed of that 340.
Dear, the maximum speed of the 340 engine is 2400 rpm Oh oh The 2400 conversion is not good on the 2100 rpm loader.
Kiss, yes.
The engine oil itself has a certain amount of consumption, and excessive consumption is the problem of burning engine oil. There are many factors that affect the burning of engine oil, such as: fuel quality, driving conditions, driving habits, maintenance habits, etc., the above reasons will aggravate the oil consumption and lead to the burning of engine oil, making the vehicle appear: >>>More

Between 380 and 3.6 million years ago.
In 1978, human footprints left in the volcanic tuff were found in the Letolier strata, belonging to two individuals, one large and one small. The footprints have raised arches, rounded heels, and the big toe is juxtaposed with the other four toes in front of the foot, all of which are human characteristics, so some scholars have classified it as a hominus. But no stone tools have been found in the same strata. >>>More
Time is a concept generated by human recording, and the natural periodicity is used as a node to record the sequence interval of changes in things, as well as to predict the future of the cycle. If things don't change, there is no way to talk about time. The main factors here are variability, periodicity, and quantitativeness. >>>More
