Abstract
A utility vehicle includes a plurality of ground-engaging members, a frame supported by the ground-engaging members, and a powertrain assembly. The powertrain assembly includes an engine, a shiftable transmission, a continuously variable transmission, and a charger. Additionally, the utility vehicle may include a cooling assembly fluidly coupled to at least the engine and the charger.
Claims23
A utility vehicle, comprising:
- a plurality of ground-engaging members;
- a frame supported by the ground-engaging members and the frame includes a front frame portion and a rear frame portion;
- an operator area having side-by-side seating supported by the frame;
- a powertrain assembly including:
- an engine having an intake manifold defining a rearward portion of the engine, a first cylinder fluidly coupled to the intake manifold, a second cylinder in line with the first cylinder and fluidly coupled to the intake manifold, and a crankshaft, the engine being configured to operate with a 270-degree firing timing;
- and
- a gaseous charger operably coupled to the engine, and the gaseous charger is a turbocharger positioned at least partially forward of the engine and at least partially rearward of the operator area;
- and
- a cooling assembly operably coupled to the powertrain assembly and having a first cooling circuit operably coupled to the engine and configured to alter a temperature of the engine and a second cooling circuit operably coupled to the gaseous charger and configured to alter a temperature of intake air received within the engine, and a portion of the first cooling circuit and a portion of the second cooling circuit are supported by the front frame portion, and the engine is supported by the rear frame portion, wherein the second cooling circuit includes a cooling device removably coupled within a portion of the intake manifold, the cooling device being at least partially rearward of the engine.
