Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1921 edition. Excerpt: ... past the piston, there will be no force to the explosion, the effectiveness of the power stroke being decreased in exact proportion to that of the gas which escapes during the compression stroke. Furthermore, when the explosion takes place the consequent expansion of the gases therefrom produces the power to drive the engine. If the valves are tight, the rings properly fitted, and the seal is maintained by the lubricant between the piston and the cylinder, none of the force (which should be used to drive the engine) will be lost through leakage.-The troubles resulting from poor compression are well known to every experienced operator and are generally manifest in hard starting and in loss of power. From the foregoing it will be readily appreciated that if there is a clearance of a 4/1000 of an inch between the piston and the cylinder, a heavier, more tenacious oil will be required than if there is only one-half that amount of clearance. The lightest oil which will maintain the piston seal is the best oil to use. It must be fluid enough to spread over the wearing surfaces quickly, leaving no dry spots. It must reach all the close fitting bearings and be free to move with very little resistance to motion. Experiments have proven that oil which is too heavy gives rise to higher temperature in the cylinder walls, and consequent higher temperature to the water in the radiator. However, if kerosene is used for fuel, heavier oil is required than if gasoline is used, because there are times (such as sudden load changes or light load) when some of the kerosene which is taken into the combustion chamber is not burned. This unburned fuel then mixes with the lubricating oil and thins it out, and unless the right lubricating oil is used it will thin...show more
