Cylinder disabling control apparatus for a multi-cylinder engine
First Claim
1. A cylinder disabling control apparatus for a multi-cylinder engine comprising:
- a variety of sensors for detecting operating conditions of an engine having a plurality of cylinders;
a catalytic converter for purifying exhaust gas of said engine; and
a cylinder disabling control means for performing cylinder disabling control on at least one specific cylinder among said plurality of cylinders by inhibiting fuel supplied to the at least one specific cylinder in accordance with the engine operating conditions;
wherein said variety of sensors includes a water temperature sensor for detecting a temperature of cooling water of said engine; and
when the temperature of cooling water upon starting of said engine is equal to or higher than a first predetermined temperature, said cylinder disabling control means performs cylinder disabling control on said at least one specific cylinder immediately after the starting of said engine until a predetermined time has elapsed.

Abstract
A cylinder disabling control apparatus for a multi-cylinder engine is provided which is capable of efficiently reducing the exhaust gas of the engine immediately after the starting thereof. The cylinder disabling control apparatus includes a variety of sensors (2, 3, 12-14, and 16), a catalytic converter (17) and a cylinder disabling control element (21) for inhibiting or stopping fuel supplied to the at least one specific cylinder in accordance with the engine operating conditions. The variety of sensors includes a water temperature sensor (14) for detecting a temperature of cooling water (WT). When the temperature (WT) upon starting of the engine 6 is equal to or higher than a first predetermined temperature (WT1), the cylinder disabling control element (21) performs cylinder disabling control on the at least one specific cylinder until a predetermined time has elapsed immediately after the starting of the engine (6).
