Title: Combustion chamber of heat insulating engine
Inventor: KAWAMURA HIDEO
IPC: F02B19/08
Filed: 1988-10-07
Abstract: PURPOSE:To make it possible to reduce smoke or NOx produced in a combustion process by forming a supply passage from a sub-combustion chamber with a fixed cross section and then, a combustion region where a combustion capacity increases at a fixed rate in a main combustion chamber. CONSTITUTION:A passage from a sub-combustion chamber is provided as a fixedly continuing combustion region. A depression 211 in a shape of a ginkgo leave is made in the upper portion of a piston head 21 where a combustion region in which the capacity of the main combustion chamber expands at a rate of secondary functional change is installed. Thereby, in an isochore region at the initial combustion of fuel, the combustion is made in the passage 32 provided next to the sub-combustion chamber 31, so that the passage 32 becomes a combustion zone kept away from a smoke production range. Combustion after the highest temperature resion is carried out in the main combustion chamber, and along a combustion zone where a fuel equivalent ratio decreases secondary-functionally without entering a production area of NOx. Therefore, production of smoke or NOx which causes air pollution can be controlled.

Title: Reversing control device for two-wheeled vehicle
Inventor: MURAKAMI RYUICHI
IPC: B62M11/06
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent a trouble due to an excessive temperature rise of a starter at reversing time, in a two-wheeled vehicle mounting a reverse system. SOLUTION: At reversing time, a temperature rise of a starter is calculated from a detected current thereof at every fixed time during starter energizing, and this temperature rise is added to a starter estimated temperature obtained in the current detection in the preceding time to determine a starter estimated temperature at this time. At the time of the starter estimated temperature reaching an allowable temperature upper limit TMAX, carrying of a current to the starter is forcedly cut off to prevent an excessive temperature rise of the starter, also to hold the starter estimated temperature to the allowable temperature upper limit TMAX to inhibit re-energing the starter.  In this way, re-energizing of the starter can be inhibited till the starter temperature lowers to to a certain degree, at forced cut off time even if a start/reverse switch is continued to be on-operated successively and a chattering phenomenon just after the forced cut off time can be prevented.
