Fuel supply system for direct injection gasoline engine
 A fuel supply system for a direct injection gasoline engine can be used in a variable fuel pressure system without using a large pulsation absorber and, as a result, is inexpensive and can be easily reduced in size. The fuel supply system for a direct injection gasoline engine includes a single-cylinder high-pressure pump, a resonator for suppressing the pressure pulsation of high-pressure fuel supplied from the high-pressure fuel pump, and a high-pressure variable regulator for variably changing the pressure of the high-pressure fuel. The fuel-supply system directly injects the high-pressure fuel into the cylinders of the engine through injectors.
