Abstract
An engine includes an intake electric S-VT configured to change a rotational phase of an intake camshaft, an exhaust electric S-VT configured to change a rotational phase of an exhaust camshaft, a fuel pump, and a supercharger driven by the engine. Both the fuel pump and the supercharger are driven by power transmitted from a crankshaft. The power is transmitted to the fuel pump via a first drive mechanism, and the power is transmitted to the supercharger via a second drive mechanism whose system is different from a system of the first drive mechanism.
Claims9
An engine with a mechanical supercharger, comprising:
- an engine provided with a camshaft and an injector;
- a variable valve mechanism mounted on the camshaft and configured to change a rotational phase of the camshaft;
- a fuel pump configured to regulate a pressure of fuel injected from the injector;
- and a mechanical supercharger driven by the engine,
- both the fuel pump and the mechanical supercharger being driven by power transmitted from an engine output shaft of the engine,
- the power being transmitted to the fuel pump via a first drive mechanism and the power being transmitted to the mechanical supercharger via a second drive mechanism whose system is different from a system of the first drive mechanism.
