Problems solved by technology

[0010] However, in gasoline direct injection engines, fuel particles of gasoline injected into the combustion chamber are adsorbed to the inner walls of the combustion chamber, piston, and spark plug, and are incompletely burned, resulting in abnormal combustion
[0011] In addition, combustion chambers, pistons and spark plugs may be damaged due to the adsorption of fuel particles, carbon deposits may occur, and delays in starting may occur, resulting in additional fuel injection, so that the durability and fuel efficiency of the engine may deteriorate

Abstract

A vehicle engine includes a cylinder block, a cylinder head installed at an upper portion of the cylinder block and forming a combustion chamber therein, a piston installed at the cylinder block and reciprocating in the cylinder block so that the volume of the combustion chamber is compressed or expanded, an injector installed at the cylinder head for injecting fuel into the combustion chamber, a spark plug installed at the cylinder head for igniting the fuel injected from the injector, and a voltage generating member installed inside the piston so that a voltage is generated by a pressure generated during a compression stroke of the piston.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit or priority of Korean Patent Application No. 10-2015-0178813 filed with the Korean Intellectual Property Office on December 15, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a vehicle engine, and more particularly, to an engine of a vehicle to which a gasoline direct injection (GDI) method is applied, which prevents fuel particles from being adsorbed into a combustion chamber and a piston, and further prevents abnormal combustion . Background technique [0004] Generally, an internal combustion engine, especially an engine with a four-stroke cycle, generates drive torque through an intake stroke, a compression stroke, an expansion stroke (expansion stroke, power stroke) and an exhaust stroke in each combustion chamber. This engine converts heat energy from fuel combustion into kinetic energy. [0...
