A compression release type engine brake includes a first opening unit and a second opening unit each including an exhaust rocker arm, an adjusting screw provided at an end portion of the exhaust rocker arm, a brake module in which brake oil is selectively and a brake piston mount portion is formed therein, a brake piston which is selectively protruded according to the oil supply inside the brake module, a reset member selectively exhausting the oil in the brake module, and a valve bridge connected to the brake piston and provided with an exhaust valve, and wherein a rocker arm protrusion is formed in the exhaust rocker arm of at least one of the first opening unit and the second opening unit, and the shaft spring presses the rocker arm protrusion and adjusts a distance between the first opening unit and the second opening unit.

Compression release type engine brake

An engine includes: a crankshaft pulley; a motor/generator mounted to a side of the engine and including a motor pulley; an auxiliary driving device pulley; a dual tensioner including a tensioner arm of which a first idler pulley is mounted to a first end of the tension arm and a second idler pulley is mounted to a second end of the tension arm, and the tensioner arm rotatable around a center of the motor/generator and a belt connecting the crankshaft pulley, the motor pulley, the auxiliary driving device pulley, the first idler pulley, and second idler pulley.

Dual tensioner and engine provided with the same

A compression release type engine brake includes an exhaust rocker arm including a roller which is mounted at one end portion thereof, and the exhaust rocker arm rotating around a rocker arm shaft by the rotation of the exhaust cam, a valve bridge disposed on the other end portion of the exhaust rocker arm and connected to an exhaust valve, a brake module mounted between the exhaust rocker arm and the valve bridge, contacting with the roller and the brake cam lobe according to inflow of selectively supplied operation oil to open the exhaust valve by the exhaust cam, and the brake module including a reset valve closing operation oil inside therein, and a reset piston slidably mounted on the second end portion of the exhaust rocker arm and protruding out of the second end portion of the exhaust rocker arm according to the supply of reset oil to push the reset valve to expel the operation oil in the brake module outwards.

A belt connection structure for a vehicle is provided. The belt connection structure includes a damper pulley mounted on a crankshaft of an engine, a water pump mounted on the engine separated in an upward direction from the damper pulley, a mild hybrid starter and generator on an upper part of the engine separated from the water pump, and an air conditioner mounted on the engine separated from the compressor damper pulley. A first belt connects the damper pulley, water pump, and mild hybrid starter and generator and a second belt connects the damper pulley and the air conditioner compressor. A first tensioner is mounted on the mild hybrid starter and generator and selectively in contact on the first belt to adjust a tension and a second tensioner is mounted on a chain cover and selectively in contact under the first belt to adjust the tension of the first belt.

Belt connecting structure for vehicle

A tensioner mounting structure for the vehicle mounted for adjusting a tension of a first belt in an engine including a water pump and a mild hybrid starter and generator that are connected to a damper pulley mounted on a crankshaft provided in a cylinder block through the first belt, and an air conditioner compressor connected to the damper pulley through a second belt, may include a first tensioner mounted on the mild hybrid starter and generator between the water pump and the mild hybrid starter and generator; and a second tensioner mounted on a chain cover mounted on the engine between the damper pulley and the mild hybrid starter and generator.
