摘要:
Supply of fuel is stopped when fuel pressure sensed by a pressure sensor provided upstream of a regulator is at a predetermined value or less to avoid abnormal combustion caused by improper adjustment of air/fuel ratio. Even slight variation of the fuel pressure is sensed by monitoring the fuel pressure in an interval after closing a fuel shut-off valve once opened to re-opening of it. In addition, an abnormal state in the fuel system is detected by comparing an accumulated value of amount of injected fuel and an estimated value of fuel consumption in the tank. Furthermore, the peak current value of the fuel injection valve is controlled so that, when the engine at a low temperature is started, lift load of the injection valve is larger than sticking force of the injection valve, thereby preventing such situation where the injection valve is frozen so that it cannot supply fuel to the engine. In this case, the engine can be smoothly started by simultaneously controlling the valve open time. Furthermore, the temperature of the regulator is properly maintained so that optimum function can be exhibited by controlling the flow rate of cooling water flowing through a water passage provided in the regulator for regulating the fuel gas pressure.

A fuel supply mechanism for a gas combustion engine has a tank filled with a gas fuel, a fuel injector having a fuel injection valve mounted on the gas combustion engine, a pipe for supplying the gas fuel from the tank to the fuel injector, a gas fuel cutoff valve in the pipe for cutting off the gas fuel flowing through the pipe, a gas fuel state detector for detecting a state of the gas fuel, and a control unit responsive to a detected signal from the gas fuel state detector for controlling the gas fuel cutoff valve and the fuel injection valve.

A fuel injection method wherein optimum fuel injection timing in a fuel-injection type gas fuel engine is determined by setting fuel injection end timing to be after the start of opening of an intake valve. That is, when injection ends in a first half of the intake valve open period the volumetric efficiency .eta.v falls and the engine output also falls, because the injection period overlaps with a period of positive pressure arising inside the intake pipe before opening of the intake valve, but when injection ends in a second half of the intake valve open period the volumetric efficiency .eta.v rises and the engine efficiency also rises, because the injection period overlaps with a period of negative pressure arising in the intake pipe during the first half of the intake value open period. Consequently, when fuel is injected during this trough in the intake port pressure, the volumetric efficiency increases and the engine output also increases by several percent.

By preventing engagement of an engaging part (clutch) under appropriate conditions, it is possible to effectively avoid the so-called surging phenomenon. When there is an engaging directive for the clutch, the rotational speed of the engaging element positioned at the output shaft side of the drive/regeneration motor (the clutch output rotational speed) is detected, and the gear ratio of the CVT is detected, and when the product of the rotational speed of the engaging element and the gear ratio of the CVT is equal to or below a predetermined value, complete engagement between the engaging elements is prevented, and control is conducted which makes the gear ratio large.

摘要:
A hybrid tuner, comprising multiple individual tuners having differing capabilities of receiving programs or channels of broadcast audio or video content, can be controlled by periodically determining the capabilities of each individual tuner to receive broadcast channels, storing such information into a guide database and then utilizing such information to select appropriate individual tuners to tune in desired programs. If the tuners that can receive a desired program are already in use, the program they are currently receiving can be switched to a different tuner to free up the tuner that can receive the desired program without interrupting the consumption of the program currently being received. When determining the capabilities of an individual tuner to receive a particular channel, one or more tokens associated with such a channel, and utilized to prevent unauthorized access to such a channel, can be obtained from the guide database and provided to the tuner.
