We all know that today's cars are generally based on gasoline, and diesel is rarely used. And the engines we commonly use now, gasoline engines are mainly used in civilian cars.
Diesel has a low ignition point and high safety. We all know that the characteristics of gasoline and diesel are very different. In terms of our lives, gasoline has a higher autoignition temperature than diesel, and gasoline burns a little better than diesel.
However, gasoline is more volatile than diesel, mainly because gasoline has smaller molecules. Therefore, gasoline is more likely to form a mixture, while diesel is not so easy to form a mixture. If it is on the battlefield and the car is filled with gasoline, then the power of ** is conceivable, but if it becomes diesel, then the probability of his ** will become smaller.
The diesel engine can respond to sudden accidents in various environments, and he can react immediately at the moment of sudden accidents.
Diesel engine can respond to sudden accidents in various environments, he can react immediately at the moment of sudden accidents, relative to cars, diesel cars are no ignition system and wearing parts spark plugs diesel is a clean fuel in foreign countries, because emissions are relatively clean, low fuel consumption, but also make many large displacement vehicles abroad choose diesel. But in China, on the contrary, diesel is an unclean fuel, and why is that? Because domestic diesel contains more wax.
The wax is easy to precipitate and condense, clogging the oil pipe and exhaust system, and the discharge is also polluted. Therefore, many cities in China prohibit the use of diesel systems for passenger cars.

1. Start the car, debug the infrared gas analyzer while heating the car, and adjust the zero according to the instructions of the instrument.
2. After the car is warmed up, press the accelerator to control the engine speed at 3500r min for 60s.
3. When the car is running at high speed until the accelerator is released and idling, insert the suction lever into the exhaust pipe (about 40cm deep).
4. After idling for 15s, start to record the results analyzed by the instrument (you can use your mobile phone to record the situation analyzed by the instrument finch for 30s).
5. Synthesize and analyze the recorded results and obtain the results.
The above is the relevant content of what is the method of diesel engine exhaust gas detection, through the above I believe we all understand, of course, if you really don't, you can ask professionals to test.

If black smoke comes out of the exhaust pipe when the diesel engine is working, it is caused by the injection of diesel fuel that has not been fully combusted. Diesel fuel that is not completely burned decomposes and polymerizes to form soot under the condition of high temperature and lack of oxygen in the combustion chamber, and the soot is not pure carbon, but a polymer with a small diameter. This solid soot reacts much more slowly than gasified fuel, and the black smoke is eliminated before it has time to burn. >>>More
There is a misunderstanding in this problem, the diesel engine is not compressed, but ignited. The ignition time of the diesel engine is the injection time of the injector, and the traditional injector uses timing gears and mechanical advancers to control the accurate injection time. The new electronically controlled common rail fuel injection system now uses a computer to control the injector's injection time. >>>More
Gasoline engine: The oil is sucked out from the fuel tank by the built-in oil pump, filtered to the pulsation reliever, and the smooth fuel is supplied to the fuel supply frame, part of which is sprayed into the cylinder for combustion, and part of it is adjusted according to the vacuum behind the throttle valve The opening of the oil pressure regulator flows back to the fuel tank, so that the fuel maintains a good and stable supply during operation. >>>More
The compression ratio of modern automobile engines, gasoline engines are generally 8 11 due to the limitation of detonation. There is no knock limit for diesel engines, and the compression ratio is generally 12 22. >>>More
Both gasoline and diesel engines belong to internal combustion engines, and both fuel is burned and the chemical energy in the fuel is converted into the mechanical energy that drives the vehicle forward by pushing the piston in the cylinder to move back and forth, so the working principle of the two is basically the same. >>>More
