Do You need warm up your engines ? (Apakah kita perlu memanaskan mesin pagi pagi sebelum kita pergi berkendara ? Myth 1: Cars should run in an idling mode for several minutes before being driven. Wrong. Modern engines do not need more than a few seconds of idling time before they can be driven safely. Moreover, the best way to warm up a car is to drive it, since that warms up the catalytic converter and other mechanical parts of the car, in addition to the engine. Myth 2: Each time you start your car you waste more gasoline than if you let it idle. Wrong. Automotive engines do not operate efficiently when they idle. Experts say there is a maximum 10 second break-even rule. If you are idling longer than 10 seconds, both you and the engine are better off if the engine is turned off and restarted. In fact,idling an engine forces it to operate in a very inefficient and gasoline-rich mode that, over time, can degrade the engine’s performance and reduce mileage. Most voluntary idling is pure waste. It wastes gasoline, and therefore money, impairs the operating efficiency of our cars, and emits additional greenhouse gases. Voluntary idling is one of the many daily actions that seem negligible but that, when taken cumulatively, can have a large impact on total emissions of carbon dioxide and on the environment more generally. The pernicious impact of idling has long been recognized. Many countries have pursued anti-idling initiatives, including a nationwide campaign in Canada and regional campaigns in Japan and Great Britain. Domestically, at least 13 states have state-wide anti-idling laws, and scores of counties and cities have their own anti-idling rules.
