Development of a System for Methane Operation in a Four Cylinder Light Duty Diesel Engine

A light duty Japanese diesel pickup and a light duty turbocharged German diesel in a lightweight two seat experimental car were converted to natural gas operation. The gaseous fuel was inducted through various experimental carburetors mounted in the air manifold system. Ignition was effected with pilot oil. Various gas metering valves and linkage to the pilot oil system were tested. Power and fuel economy were measured.
