Abstract

1325773 Cooling I C engines; engine casings H LIST 1 Sept 1970 [8 Sept 1969] 41753/70 Heading F1B An I C engine has a sound-proofing casing which comprises first casing members 23 and 30 mounted directly on and spaced from the engine and second casing members 34, 35, 36 and 37 attached to the first casing members which are removable for access to those parts of the engine and its auxiliaries which require periodic maintenance. The member 23 has the intake pipe 18, 18<SP>1</SP> and the exhaust pipe 27 extending therethrough. The members 23 and 30 are connected to the cylinder head 4 and the crankcase 1 and fly-wheel housing 14, respectively, by vibration damping supports 24, 31, 33, e.g. of rubber. Side casing members 36 and 37 which may be directly connected at the front and rear ends of the engine or connected by separate casing members have apertures with elastic seals 40 through which engine supports 2 extend. A blower impeller 8 at one end of the crank-shaft 6 draws air into the casing through a silencer 41 and the air is exhausted through a silencer 39. The inlet and exhaust pipes include vibration damping connecting portions 26 and 28 within the casing and the fan drive shaft 11 extends through a sound-absorbing sleeve 43. In a further embodiment, Figs.3 and 4 (not shown), the exhaust manifold (20<SP>1</SP>) has a water cooling jacket (44) with an outlet pipe (45), including a vibration damping connecting portion (46), extending through the casing member 23. The air exhaust silencer (47) surrounds the exhaust pipe 27 with the air exhaust passage (48) therebetween and the engine sump (15<SP>1</SP>), which extends through an aperture containing a seal (40) in the casing member 30, includes a vibration damper (49) connecting portions of the sump within the casing. In another embodiment, Fig. 5 (not shown), the engine has a skeletal crank-case (53) and the sound-proofing casing provides an oil-tight housing for the engine. Two casing members (54 and 55) (not shown) Fig. 5, are directly mounted on the engine and removable casing members (56, 57 and 58) cover the valve gear and the fuel injection pump (16) and form the sump, respectively.
