Abstract
Throttle tip-in and tip-out tests on a 2.0 litre passenger car engine were performed using four different natural gas fuelling systems an air-valve or variable restriction type mixer, a venturi type mixer, central fuel injection, and port fuel injection. The in-cylinder fuel-air equivalence ratio, ϕ, was measured using a fast response flame ionization detector sampling about 7 mm from the spark plug gap. The data reveal characteristics of each fuel system's in-cylinder fuel-air ratio response and torque response.
