Abstract
The technology disclosed herein relates to a grounds maintenance vehicle. The grounds maintenance vehicle has an engine and an engine shroud defining a cooling volume around the engine. The shroud defines a shroud intake. An engine oil conduit extends from the engine and a heat exchanger is coupled to the engine oil conduit.
Claims21
A grounds maintenance vehicle comprising:
- an engine enclosure defining an air intake area, wherein a screen extends across the air intake area, and the engine enclosure comprising at least one inner enclosure surface defining at least one airspace volume between the air intake area and the inner enclosure surface;
- an engine disposed in the engine enclosure;
- an engine shroud defining an engine cooling volume about a portion of the engine;
- and
- a heat exchanger disposed in the engine enclosure, the heat exchanger configured to receive engine oil, wherein the vehicle defines a first airflow pathway extending from the air intake area to the engine shroud, and a second airflow pathway extending from the air intake area through the heat exchanger, wherein the first airflow pathway and the second airflow pathway are arranged in parallel.

2 more elements
A grounds maintenance vehicle comprising:
- a vehicle frame;
- drive wheels coupled to the vehicle frame;
- an implement coupled to the vehicle frame;
- an engine enclosure coupled to the vehicle frame, wherein the engine enclosure defines an engine cavity and an airspace volume isolated from the engine cavity within the engine enclosure, and where the engine enclosure comprises a screened area between the airspace volume and an ambient environment;
- an engine disposed in the engine cavity of the engine enclosure;
- a first engine cooling system comprising an engine shroud defining an engine cooling volume about a portion of the engine, wherein the first engine cooling system defines a first airflow pathway extending from the screened area to the engine cavity via the engine cooling volume;
- a second engine cooling system comprising a heat exchanger, an oil flow pathway from the engine to the heat exchanger, and a second airflow pathway extending from the screened area to the engine cavity through the heat exchanger;
- and
- a combustion intake extending from the shroud into the engine.
