초록

A system and method for controlling operation of a multiple cylinder direct injection internal combustion engine include injecting fuel directly into the combustion chamber during the exhaust stroke at high engine speeds and loads to reduce the effect of intake airflow on the injection spray and improve fuel-air mixture homogeneity.

대표
청구항

What is claimed: 1. An engine comprising: a fuel injector for each cylinder that injects fuel directly into the cylinder; and a controller that generates control signals at least during high engine speed/load conditions to start and end a first fuel injection during an exhaust stroke that mixes with inducted air and fuel from at least a second fuel injection starting during at least one of an intake stroke and a compression stroke of the same cycle. 2. The engine of claim 1 wherein the first and subsequent fuel injections have a fuel pressure of less...
