L'invention concerne un groupe moteur (1) comprenant un moteur à combustion (2) duquel débouche, d'une part, un collecteur d'échappement haute pression (9) alimentant une ligne d'échappement (11), et, d'autre part, un collecteur d'échappement basse pression (10) alimentant une ligne de recirculation (14). Selon l'invention, le groupe moteur (1) comprend un réservoir (29) à gaz qui est relié au moteur (2) par une vanne d'isolation (31) pouvant prendre une configuration de communication permettant une circulation des gaz entre le moteur (2) et le réservoir (29), et une configuration d'isolation empêchant cette circulation.
Abstract:
A straddle-type vehicle (1) according to the present invention includes a single-cylinder four-cycle engine (10). The engine (10) includes an exhaust gas re-circulation device (101). The exhaust gas re-circulation device (101) is communicated with an exhaust port (31). The exhaust gas comes into the storage container (100) in the exhaust gas re-circulation device (101) when the exhaust valve (32) is open in an exhaust stroke. When the exhaust valve (32) is open in an intake stroke after the top dead center, the exhaust gas is discharged from the storage container (100) into the combustion chamber (40).
Abstract:
The invention relates to a method for operating a combustion system (1), a fuel (6) being burned in at least one combustion chamber (2) with a carrier gas (7) containing oxygen while releasing an exhaust gas flow (8), ambient air (10) being separated into a product gas (12) enriched with oxygen and an exhaust air (13) enriched with nitrogen, a gas flow (9) being separated from the exhaust gas flow (8) and recirculated into the combustion chamber (2), the recirculated gas flow (9) being mixed with a product gas flow (12a) of the product gas (12) into the carrier gas (7), and the carrier gas (7) and the fuel (6) being fed into the combustion chamber (2) separately. According to the invention, the argon concentration in the recirculated gas flow (9) and/or in the carrier gas (7) is measured.

Abstract:
Cylinders of an internal combustion engine are provided with an exhaust port that is opened when the piston approaches bottom dead center. Exhaust in the cylinder at the end of the power stroke flows to an EGR tank for containment and cooling. During the intake stroke as the piston approaches bottom dead center, the exhaust port is reopened allowing gas from the EGR tank to flow into the cylinder as a portion of the charge prior to compression. Alternatively, the exhaust port on a first cylinder is connected to the exhaust port on a second cylinder to allow exhaust gas from the power stroke on the first cylinder to flow into the intake stroke on the second cylinder. Pulsed turbocharger systems comprise an internal combustion engine comprising a piston cylinder and a piston slidably disposed within the cylinder. The cylinder includes an exhaust gas port that is disposed through a wall section of the cylinder. The exhaust gas port is positioned near a bottom portion of the cylinder such that: (1) an opening of the port is exposed when the piston is at the bottom of its stroke within the cylinder; and (2) an opening of the port is covered when the piston is moved towards the top of its stroke. A turbocharger that is connected to the engine and comprises a turbine wheel that is in exhaust gas flow communication with the exhaust gas port. Pulsed exhaust gas exits the piston cylinder through the exhaust port, when the piston is near a bottom portion of its work stroke. This pulsed exhaust gas is directed to the turbine wheel to cause the turbocharger to produce boost air for directing to the engine.
Abstract:
An internal combustion engine having a compressed air assisted fuel injection system (20). The injection system has a compressed air accumulator (34) with a first aperture (30) into the cylinder of the engine and a second aperture (38) into the crankcase (18) of the engine. The two apertures are located at opposite ends of the accumulator and the accumulator has a tube shape. The accumulator blows off pressure every time one of the ports into the cylinder is closed. The tube shape of the accumulator forms a tuned reflection pipe for a compression wave from the cylinder to generate a reflected compression wave for assisting in delivering fuel and air into the cylinder. The two apertures are adapted to be opened and closed by the piston head of the engine.
