ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18370232 titled 'ENGINE
Simplified Explanation
The patent application describes an engine that ignites an air-fuel mixture with an electric spark. The engine includes a cylinder head with a chamber partition wall, a fuel injector, an air injector, an ignition device, and a control system. During a warm-up operation, fuel is injected throughout a first period, followed by air injection throughout a second period that overlaps with the first period. The electric discharge is caused after the fuel injection during the power stroke.
- Cylinder head with chamber partition wall and through holes
- Fuel injector for main combustion chamber
- Air injector for sub-combustion chamber
- Ignition device for electric discharge
- Control system for fuel, air injectors, and ignition device

Original Abstract Submitted
An engine is configured to ignite an air-fuel mixture with an electric spark to ignite an air-fuel mixture. The engine includes: a cylinder head including a chamber partition wall having through holes and defining a main combustion chamber and a sub-combustion chamber; a fuel injector that injects fuel into the main combustion chamber; an air injector that injects air into the sub-combustion chamber; an ignition device causes an electric discharge between an ignition electrode and the chamber partition wall; and a control system that controls the fuel and air injectors, and the ignition device. At a compression stroke during a warm-up operation, the fuel is injected throughout a first period, and the air is injected throughout a second period at least partially overlapping the first period. At a power stroke during the warm-up operation, the electric discharge is caused after the fuel is injected.
