Title: Intake valve controller for engine
Inventor: SHIMIZU HIROKAZU
IPC: F02D41/06
Filed: 2001-06-21
Abstract: PROBLEM TO BE SOLVED: To promote fuel atomization by controlling an opening characteristic of an intake valve from the start to the fast idle, thereby improving emission. SOLUTION: When water temperature falls within the prescribed low temperature range (S11), an idle switch is on (S12), and the time is within a prescribed range after the start (S13), the lift quantity of the intake valve is lowered (S14) by a variable valve mechanism VEL continuously changing lift quantity and operating angle of an intake valve. The valve timing is delayed by a variable valve timing mechanism VTC continuously changing the valve timing of the intake valve (S15). The fuel injection timing is controlled during intake process (S16). By so doing, while intake flow velocity is accelerated to promote fuel atomization, fuel wall flow inside a cylinder is decreased to improve emission.

Title: Generator controller for hybrid vehicle
Inventor: YANASE HISASHI
IPC: B60L50/15
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a generator controller for a hybrid vehicle capable, on top of being capable of surely preventing troubles including a breakdown caused by temperature rise, of improving fuel efficiency and emission characteristics, by applying a generator of as small a capacity as possible for required power generation capacity. SOLUTION: If generator temperature T is caused to rise due to overheating, temperature rise is suppressed by limiting the operating range of the generator, accordingly from a short-time rated range to a continuous rated one of a low- heating operation side. Accordingly, the rotational speed of the generator is increased from N1 to N2 for securing required power generation capacity. Use of the short-time rated range makes the generator capacity to be reducible.
