    摘要： A full time lean air fuel mixture running spark ignited air cooled aircraft piston engine. In one embodiment, a drop-in substitution is provided for an equivalent make, model, and engine size, wherein the new, rebuilt, or reconfigured engine provides as much or more horsepower when compared to the original engine, but runs at a lean air fuel ratio condition during normal operating modes, including takeoff, climb, and cruise, thus saving significantly on fuel. In yet another embodiment, a drop-in substitution having a somewhat larger cylinder displacement volume may be provided to attain equivalent or enhanced maximum horsepower while operating at lean air fuel ratios.Enhanced engine life may be anticipated, since cylinder head temperatures (CHTs) may be reduced, compared to engines using rich air fuel ratios for climb and cruise conditions. Aircraft using such engines are also disclosed.

    摘要： A method is provided for controlling the combustion parameters of an internal combustion engine without a PCV solenoid during a boil-off condition. The methodology records the temperature of the engine when the vehicle is turned off. When the vehicle is restarted, the methodology determines the amount the engine has cooled since it was shut down. Based on the difference in engine temperature and the current engine temperature, the methodology determines the amount of boil-off corruption remaining. The methodology then determines a new boil-off corruption fuel multiplier based on the amount of boil-off corruption remaining. The new boil-off corruption fuel multiplier is used to modify fuel control until the boil-off condition ceases.

    摘要： The combination of an intake air supply system with an internal combustion engine having a charge air cooler, a cylinder charging air intake and an exhaust discharge is provided. The intake air supply system includes a Roots-type positive displacement blower having inlet and outlet means and an exhaust gas driven turbo-compressor connected in series with the blower. The intake air supply system further includes a bypass passage connecting the blower inlet and outlet and a valve in the bypass passage to control the flow of fluid through the bypass. The valve is operative to open and close the bypass passage in response to engine operating parameters and to modulate the flow area of the passage in response to the same engine operating parameters so as to infinitely vary the flow area between the open and closed positions of the valve. The valve is modulated to operatively maintain the bypass passage at least partially open at engine idle, whereby the valve means permits bypass flow to recirculate air flow from the blower outlet to the inlet to reduce or limit the engine power absorbed by the blower or to conduct additional air flow around the blower directly from the turbo-compressor to the engine intake to avoid the restriction of the blower to increased charging air flow. A single valve means thus provides a dual function capability.
