THREE-CYLINDER ENGINE WITH DISABLED CYLINDER AND METHOD FOR ITS OPERATION

摘要

1. Three-cylinder in-line reciprocating reciprocating internal combustion engine containing two external primary cylinders and one secondary cylinder located between two external primary cylinders, where each of the cylinders is a sliding support for the corresponding piston, functionally connected by a corresponding connecting rod to the corresponding elbow of the three-knee cranked shaft with cranks located in the same plane, and the elbows for the two primary cylinders are in phase o, and the elbow for the secondary cylinder is phase-shifted relative to the two primary cylinders by 180 degrees, and the secondary cylinder can be selectively deactivated. 2. The engine of claim 1, wherein the secondary cylinder can be deactivated to increase fuel economy. The engine according to claim 1 or 2, wherein the secondary cylinder can be deactivated to increase at least one of the following: temperature of exhaust gases, lubricating oil and coolant in the engine. The engine according to claim 1 or 2, made with the possibility of a stroke in one of the two primary cylinders at each full revolution of the crankshaft, and the stroke of the secondary cylinder does not coincide in phase with the stroke of the primary cylinders. The engine according to claim 1 or 2, in which the deactivation of the secondary cylinder can be carried out by stopping the supply of fuel to the secondary cylinder. The engine according to claim 1 or 2, in which the secondary cylinder has at least one inlet valve and at least one exhaust valve, and the deactivation of the secondary cylinder is carried out using
