Automobile double overhead camshaft

1 The double overhead camshaft is DOHC, and there are two camshafts in the cylinder head to control the opening and closing of the intake valve and exhaust valve. This is relative to SOHC's single overhead camshaft. The obvious difference between them is the number of camshafts.

2. Turbocharged Turbo has nothing to do with any camshaft. Turbocharging is the reuse of exhaust gas, which uses the inertia impulse of exhaust gas discharged by the engine to push the turbine in the turbine chamber, and compresses more air into the cylinder to increase the fuel quantity, thus improving the work of combustion. It consumes less oil and generates more electricity. Improve fuel economy

3 Throttle valve (throttle valve) is the control valve. When you step on the accelerator, it is actually the intake valve that opens. Traditionally, the valve opening is controlled by mechanical structure. The electronically controlled throttle, as its name implies, is not a mechanical steel wire or gear. When you step on the accelerator, the valve is controlled by the electronic control system.

4。 Variable eddy current control system is equivalent to "naturally aspirated pressurization". By controlling the throttle valve, the intake air of the engine forms different "intake vortex" under different working conditions, so that the atomized fuel sprayed by the injector can be better mixed with the air to ensure the most complete combustion.

I didn't mean it personally when I answered you. Is it easy to type so many words?
