<p>An internal combustion engine, which has soundproofing cowling, uses the space between the sidewalls of the cylinder block and the cowling to provide a reservoir for a liquid lubricant media. A cover cap is provided over the fuel injection and valve timing mechanisms, and the space between the cover cap and the cowling, which is over the top of the cylinder head, provides a chamber for receiving coolant form the engine cooling system. The large surface area of the cowling along the sides of the cylinder block accommodates the transfer of heat from the lubricant to the atmosphere. In addition both the lubricant and the coolant serve as sound deadening medias in the sidewall reservoirs and in the overhead chamber.</p> |
