Abstract
Abstract The invention provides an engine cooling system for a water cooled engine in a motor vehicle, comprising a radiator 18 totally enclosed within ducting such that air flowing through the radiator does not otherwise pass through the engine compartment. The radiator 18 is arranged within a branched ducting with two outlet openings, one branch being fan 20 assisted and the other opening into a region 28 of low pressure at the front underside of the vehicle. An undershield 22 serves to enclose the engine and separate air flow paths are formed for cooling the oil sump, the top of the engine and the exhaust manifold.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A motor vehicle engine cooling system, comprising a radiator (18) totally enclosed within ducting such that air flowing through the radiator (18) does not otherwise pass through the engine (24) compartment, and further passages for allowing ambient air to enter and leave the engine compartment, characterised in that the ducting of the radiator (18) has a forward facing inlet (26) upstream of the radiator (18) which opens at the front of the vehicle, a first outlet (28) facing forwards and disposed adjacent a speed spoiler (12) at the front of the vehicle and connected to the radiator by a branch of the ducting containing a non-return valve (14) and a second outlet (30) disposed on the underside of the vehicle and connected to the radiator (18) by a branch of the ducting containing a power driven fan (20).
Claim 2
Dependent Claim
138 words
A motor vehicle engine cooling system, comprising a radiator (18) totally enclosed within ducting such that air flowing through the radiator (18) does not otherwise pass through the engine (24) compartment, and further passages for allowing ambient air to enter and leave the engine compartment, characterised in that the ducting of the radiator (18) has a forward facing inlet (26) upstream of the radiator (18) which opens at the front of the vehicle, a first outlet (28) facing forwards and disposed adjacent a speed spoiler (12) at the front of the vehicle and connected to the radiator by a branch of the ducting containing a non-return valve (14) and a second outlet (30) disposed on the underside of the vehicle and connected to the radiator (18) by a branch of the ducting containing a power driven fan (20).
Claim 3
Dependent Claim
41 words
A motor vehicle cooling system as claimed in claim 1, wherein the positive pressure inlet to the duct is located in the front bumper (10), the latter being shaped to provide a ram effect for forcing air into the duct (26).
Claim 4
Dependent Claim
29 words
A motor vehicle cooling system as claimed in claim 1 or 2, wherein two axial flow fans (20) are arranged laterally side by side downstream of the radiator (18).
