getting zero miles per gallon. When idling, a diesel engine consumes about one gallon of fuel per hour. Needlessly letting an engine idle wastes both fuel and money. Since the diesel fuel is also a coolant for the injectors, the injector tips can be burned if the engine idles at a low r.p.m. How does today’s diesel engine differ from those from years ago? Every diesel engine has an r.p.m. range within which it must be operated to generate the necessary torque and power to move the vehicle and load and to operate with maximum efficiency. Today's diesel engines generate torque and power over a much wider range of engine r.p.m. than was formerly the case. A professional driver always follows the engine manufacturer's recommenda- tions for the proper engine speed at which to shift up or down. What are the undesirable effects of tampering with the enginet Pe ‘Tampering with the engine's settings can increase fuel consump- tion by allowing the engine to exceed its design speed. This could result in engine failure and leave the driver stranded. The Envi- ronmental Protection Agency (EPA) can also fine companies up to $45,268 per noncompliant vehicle or engine, $4,527 per tampering event or sale of defeat device, and $45,268 per day for reporting and recordkeeping violations. Why is the presence of carbon monoxide in a motor vehicle so dangerous? Carbon monoxide, which is produced when an engine burns carbon- based fuels, is a deadly poison when inhaled in excessive amounts and is virtually impossible to detect because it is color- less, odorless and tasteless. Carbon monoxide is formed at lower concentrations by diesel engines than by gasoline engines. What are the first symptoms of carbon monoxide poisoning? Pe The first obvious symptoms of carbon monoxide poisoning are drowsiness, lightheadedness, and/or headache. r4
