An intake system for a supercharged hydrogen-ammonia hybrid fuel engine

Abstract

The application discloses an air intake system for a supercharged hydrogen-ammonia mixed fuel engine, and aims at solving the hydrogen-ammonia fuel contradictory characteristics and the cold start problem of the supercharged engine. The core structure comprises an integrated die-cast high-thermal-conductivity aluminum alloy manifold body, and the body is internally integrated with a main air intake cavity, an ammonia gas supply rail, a pre-embedded PTC electric heating wire, a hydrogen injection interface, a mixing enhancement structure, and a closed-loop control system composed of multiple sensors and an ECU. The ECU controls the cooling intensity, the heating heat source and the electric auxiliary heating power according to the working conditions, realizes hydrogen early combustion prevention, ammonia full gasification, cold start rapid response and full working condition uniform mixing. The application has high integration degree and low energy consumption, and enables the supercharged hydrogen-ammonia engine to stably operate in full working conditions.
