WHY IT IS IMPORTANT TO REDUCE AND CONTROL ENGINE'S HEAT? Heat causes valve springs, wrist pins, cylinder walls, pistons and piston rings and other moving parts to expand, all at the same time and against the opposing directions of each other's expansion. This results in hard friction which causes immense wear and tear. Engines begin to stall, leak escaping oil, loose power and the ability of pistons to combust fuel diminishes, leading to unburned fuel passing into the exhaust system, causing backfires and failure of engine to start. Ultimately, all these result in scratches and twists and cause the engine to freeze or melt the rings and pistons. To rebuild such engine or replace it, cost big money. Heat causes engine gaskets to become dislodged because of the rapid high heating and then sudden cooling down. This causes oil to pass into cooling water, and the water passing into the oil chamber. This, aborts proper operation, even prevents the engine from starting. To remedy this, engines have to be rebuilt, completely changed if cracked, or its gaskets replaced with all other necessary adjustments, expenses and the down-time. In developing countries, this cost both individuals and their countries a great deal of desperately needed hard currency. High heat causes poor performance, inefficiency, chronic overheating and high consumption of fuel, as well as smoke, exhaust and oil pollution. Over the long haul, heat severely shortens the life of engines and under the hood components, which result in additional dead cars, tractors and trucks, with the wasteful import of spare parts. |
