The water injection system is cold water injected into the interior of the engine head, pushed by the pressure of the pump, so that cold water enters in the form of fine mist into the cylinder together with the combustion gas. The maximum object of cooling, also can increase the compression ratio, the effective control of the intake air temperature, reducing the likelihood of occurrence of knocking in the engine.
1. The water injection system Term analysis
The water injection system is cold water injected into the interior of the engine head, by pushing the pressurizing pump so that cold water enters in the form of very fine mist together with the combustion gas within the cylinder. The maximum object of cooling, also can increase the compression ratio, the effective control of the intake air temperature, reducing the likelihood of occurrence of knocking in the engine.
2. The principle of the water injection system
of the air intake
through a turbine high pressure turbine vehicle, the temperature rises rapidly, high intake air temperature will seriously affect the combustion efficiency, leading to reach the corresponding power of the engine . The main purpose is to reduce the water injection system cylinder temperature. While the water molecules are vaporized gasoline energy required six times, and therefore the same cooling water is far greater than the ambient gas, the temperature can take away a lot. The water injection system after the atomized mist is injected into the cylinder, it can effectively reduce the temperature in the cylinder, once the temperature decreases, can effectively enhance the energy efficiency of the engine.
3. Advantage of the water injection system
the water injection system can bring better combustion, less fuel consumption, emissions and more environmental advantages.
The water injection system on behalf of the BMW model M4 GTS, mounted 3.0T L6 twin-turbo engine having 500 horsepower and 600 Nm of torque, a 7-speed double clutch gearbox, Niubo North Central Green score: 7 minutes 28 seconds, faster than the normal version M4 22 seconds. 0-100km / h acceleration 3.8 seconds.
