Q: What is the engine ECM?
So, the working state of the engine is a closed loop control, and here are a few simple examples: ECU by setting the working law of the engine, MAP. Then add the oxygen sensor in the exhaust pipe, judge the operating state of the engine by oxygen sensor, oil and more or less in the cylinder; adding knock sensor, ignition timing is judged ahead or delayed; join at the outlet water temperature sensor can determine the engine combustion chamber temperature is normal to correct the amount of oil, protect the engine and so on. These basic data are sent to the ECU via a wire harness, and the ECU constantly adjusts fuel injection and ignition timing based on their feedback.
Q: Why is the power of a model engine different?
Different manufacturers of manufacturing levels will be different, and in order to control the manufacturing costs will be different in the selection, the results will lead to engine power performance differences.
Q: What is engine resonance?
Engine vibration is an important indicator of the quality of engine work.
Q: What's the difference between the engine 1.8T and the 1.8L?
When the engine speed, exhaust gas speed and turbine speed synchronous speed, the air on the degree of compression to increase the air intake of the engine will be increased accordingly, can increase the output power of the engine.
Q: What does the engine automatically mean?
Bora TDI uses the latest high-pressure fuel injection technology - pump injection system.
Q: Cause and analysis of excessive fuel consumption in engine
Let's sum up some of the main fuel consumption in our daily driving. We hope it will help you save your oil. Man will artificially increase the power loss of the engine. At the same time, excessive braking will increase the number of starts, and the fuel consumption at the beginning
Q: Is the load and torque of the engine the same thing?
Turn, for example, some of the marine diesel engine limit speed are super but 1000 turn, it would not be such a engine is a failure?
Q: What are the six engines?
An engine is a device that converts the chemical energy of fuel combustion into mechanical energy. Starting from the mechanical principle, the engine consists of six major parts (cylinder block, cylinder head, Bush, piston, valve, connecting rod, etc.), that is to say, "six matching"".
Q: Cloud 490 engine how
Among them, the casting production line is from Switzerland into the GF modeling line, supplemented by the domestic advanced equipment, the United States melting equipment, the German cold box-core equipment and foreign direct reading spectrometer and other testing facilities.
Q: What are the performance differences between the four engines of the L, V, W, and H?
Inline 4 cylinder engines are widely used in engines with a displacement of 2.2 liters or less. Inline 6 cylinder engine, the current leader is the famous BMW, BMW inline 6 cylinder engine, condensed today's mass production engine of the top technology, can be called "straight 6 cylinder" peak.
