What's wrong with the engine water?

The water intake state of the engine is as follows: 1. When a single-cylinder diesel engine is started in winter, engine flooding is a common phenomenon. Also known as "drowning", that is, the engine can't start normally. The reason is that the temperature is too low in winter, the compression ratio can't reach when the engine starts, and the diesel can't burn normally. The solution is not to feed oil, but to preheat at idle speed to discharge excess oil in the cylinder. 2. EFI engine will also have the phenomenon of "cylinder filling". The solution is to keep stepping on the accelerator pedal and turn on the motor for 5 seconds, with an interval of 3 seconds, and repeat twice. The problem can basically be solved. If there is too much fuel, remove the spark plug for cleaning; 3. Principle: Before the ignition switch is turned ON-SI, when the engine speed is lower than 500 rpm and the ECU receives the signal that the TPS sensor (throttle position sensor) is fully open, the ECU will control the fuel injector to stop injecting fuel. Excess fuel in the cylinder will be discharged from the cylinder when starting; 4. Until the mixture in the cylinder returns to normal proportion. At this time, the spark can ignite the fuel in the cylinder, and the number of revolutions begins to rise. When the speed exceeds 500 rpm, ECU recognizes the end of the engine overflow clearance function. Start to control the fuel injector to work, and the engine starts to run normally.
