Abstract
An engine includes a plurality of cylinders, a gas chamber, and a heat shielding member. The plurality of cylinders are provided along a crankshaft. The gas chamber extends from a first end portion toward a second end portion in a direction of an axial line of the crankshaft and distributes gas into the plurality of cylinders. The heat shielding member is provided in the gas chamber. The heat shielding member extends from the first end portion toward the second end portion and shields heat radiated from an inner wall surface of the gas chamber.
Claims5
An engine comprising:
- a plurality of cylinders provided along a crankshaft;
- a gas chamber configured to extend from a first end portion toward a second end portion in a direction of an axial line of the crankshaft and to distribute gas into the plurality of cylinders;
- and
- a heat shielding member provided in the gas chamber and configured to extend from the first end portion toward the second end portion and to shield heat radiated from an inner wall surface of the gas chamber
- wherein a plurality of air supply pipes that supply the gas in the gas chamber to the plurality of cylinders, respectively, are connected to an upper wall of the gas chamber or a plurality of lid members that respectively closes a plurality of openings formed in the upper wall, and
- the engine further comprises a cooling device configured to cause coolant cooling the cylinders to flow from the first end portion toward the second end portion in the direction of the axial line, wherein the heat shielding member partitions an internal space of the gas chamber into a first space configured to guide the gas introduced into the gas chamber from the first end portion toward the second end portion, and a second space configured to communicate with the first space and to distribute the gas flowing in from the first space into the plurality of cylinders while guiding the gas from the second end portion toward the first end portion.
An engine comprising:
- a plurality of cylinders provided along a crankshaft;
- a gas chamber configured to extend from a first end portion toward a second end portion in a direction of an axial line of the crankshaft and to distribute gas into the plurality of cylinders;
- and
- a heat shielding member provided in the gas chamber and configured to extend from the first end portion toward the second end portion and to shield heat radiated from an inner wall surface of the gas chamber
- wherein a plurality of air supply pipes that supply the gas in the gas chamber to the plurality of cylinders, respectively, are connected to an upper wall of the gas chamber or a plurality of lid members that respectively closes a plurality of openings formed in the upper wall, and
- the engine further comprises a supercharger configured to compress the gas introduced from the outside, a gas cooler configured to cool the gas compressed by the supercharger before being introduced into the gas chamber, and a guide surface provided in the gas chamber and configured to guide condensed water contained in the gas introduced into the gas chamber.
