Title:
DUAL-FUEL INTELLIGENT COMBUSTION SYSTEM AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/274184
Kind Code:
A1
Abstract:
A dual-fuel intelligent combustion system, comprising a cylinder body (1), a cylinder cover (3), a piston (2), a methanol fuel injector (5), a diesel injector (6) and electronic control units (ECU), wherein the cylinder body (1), the cylinder cover (3) and the piston (2) form a combustion chamber; the cylinder cover (3) is arranged directly above the cylinder body (1); the piston (2) is arranged in the cylinder body (1); the combustion chamber is provided with an air inlet channel (7) and an air outlet channel (4); the combustion chamber is internally provided with the methanol fuel injector (5) for injecting alcohol fuel into a cylinder and the diesel injector (6) for injecting ignition fuel diesel into the cylinder; and the methanol fuel injector (5) and the diesel injector (6) are controlled by two electronic control units (ECU) respectively. The present invention further relates to a control method for the dual-fuel intelligent combustion system. According to the dual-fuel intelligent combustion system and the control method therefor, the problem of the cold start of methanol fuel being difficult is effectively solved, the combustion efficiency and thermal efficiency of an engine are increased, and the fuel economy and discharge cleanliness of the engine are improved.
