摘要： Vibration generated by a secondary inertia couple based on the lateral pressures from the pistons (32) of an offset in-line four cylinder engine is reduced. A reference line (L1) is established that passes through the shaft center of the crankshaft (30) and is parallel to the cylinder axes of the four cylinders as viewed in the axial direction of the crankshaft. As viewed in the axial direction of the crankshaft, the direction in which the reference line extends is referred to as first direction, and the direction perpendicular to the first direction is referred to as second direction. At least one of the following (1) and (2) applies so as to reduce vibration generated by a secondary component of an inertia couple based on the lateral pressures from the four pistons.
(1) the distance between the shaft center (40C) of the first balancer shaft (40) and the reference line as measured in the second direction may be different from the distance between the shaft center of the second balancer shaft (42) and the reference line as measured in the second direction, and
(2) the magnitude of the first unbalancing portion (40A) may be different from the magnitude of the second unbalancing portion (42A).

摘要： A four-cylinder engine includes a cylinder body (3), a cylinder head (4), and an ignition device (27) including spark plugs (14). The engine also includes an intake device (16) connected to intake ports (9), an exhaust device (23) connected to exhaust ports (10), four pistons (6), and a crankshaft (8) connected to the pistons (6) by connecting rods (7). Explosion intervals of the four cylinders are 270°, 180°, 90°, and 180° as crank angles. The engine further includes an discomfort eliminator (35) which, when the engine speed is lower than a predetermined value, makes the indicated mean effective pressure of at least one of two cylinders having an explosion interval of 90° lower than the indicated mean effective pressures of other cylinders having an explosion interval of not 90°. This invention can provide a four-cylinder engine which causes unequal-interval explosions but produces little change in driving energy per unit time in an operating state in which an occupant is liable to feel torque fluctuations.
