, Due to limited conditions, many of us who are in the driving school in the old classic cars with the driving skills of learning. And learn driving skills at the same time, some people have to learn bad driving habits over. The so-called bad driving habits, that is some classic cars suitable for the operation, and in relatively high-tech modern car but will cause damage to the driving habits. In a sense, the right driving habits than any form of repair and maintenance. A clutch control method is outdated feet school early and repeatedly practicing the feet clutch car method you may already have been shifting back to the master of the bar. No wonder, even the most expensive truck now have adopted the fully synchronous transmission,[link widoczny dla zalogowanych], the shift who would bother you when? But extend transmission life point of view, legs clutch, especially when the downshift on the gas or H good. First, it can reduce the synchronizer ring wear and prolong transmission life; addition, it can significantly reduce the impact of gear shifting, extending the life of driveline components. In an emergency, such as brake failure, relying on quick substitutions feet low clutch and use the engine to brake. There is a exaggeration, feet clutch shift is the most practical from the driving school to learn a trick with a file of 12 neutral or sliding sliding sliding gap was regarded as a fuel-saving tips for drivers of many of the old one. In the old carburetor car, this practice can really fuel efficient. The reason is simple, when the engine fuel consumption 2000r/min definitely better than idling when the fuel consumption, and in the EFI car to an entirely different matter. Most of the electronic control of fuel injection systems have Decelerating off oil function. Specifically, when the accelerator pedal is released completely,[link widoczny dla zalogowanych], the engine speed higher than 2000r/min, the computer will automatically stop the oil supply; when the machine's speed dropped to below 1000r/min, the computer and then resume supply. Obviously, if the zone file EFI car sliding, you can slide a few hundred meters without consuming a drop of oil, as well as the ability to engine brake, but if the gap slide, is not only dangerous, but also for the maintenance of the additional spend a lot of idle fuel. In contrast, an approach which is more cost-effective it? Said above, the model with a manual. Automatic transmission-equipped car, sliding gap, especially when the gap flameout glide speed is not permitted, because it is not only dangerous, but also may damage automatic transmission. 3 idle the engine warm-up or warm-up driving is the normal operating temperature of about 9o ℃. After starting the cooling water temperature rise from ambient temperature to normal operating temperature of the process known as preheating. Most people are used to maintain the practice is to let the engine idle, the temperature slowly rising, and so to reach the normal temperature before the car drove away,[link widoczny dla zalogowanych], this approach not only become a habit, but also appeared in many textbooks. In the fuel injection system and equipped with catalytic converters on cars, this approach is not only unnecessary, but also harmful. The correct approach is, the engine starts, as long as you can maintain a steady speed to take the car off in the first few kilometers, the proper control about speed, so the normal temperature after full acceleration. Why? Because from the perspective of protecting the engine, warm-up time as short as possible. Vehicles in the warm-up time than stay still idle warm-up time much shortened. Old-fashioned carburetor engine operating temperature is reached before the fuel supply systems are often not working properly, fuel atomization is not good, this time if the force driving, speed instability will naturally appear, turn off heat, which are not normal, it must wait for the machine thermal up before it can travel. In other words,[link widoczny dla zalogowanych], idle warm-up is a last resort, and advanced fuel injection systems rely on sensors to measure water temperature, computer-controlled fuel injection nozzle is not only accurate but also significantly improved fuel atomization. Therefore, after starting only a short time to live the machine speed can be stabilized, the vehicle driving immediately. On the other hand, the normal operation of catalytic converter temperature is about 600 ℃, from the perspective of longevity, it is also the warm-up time as short as possible. Engine idling, the less fuel injection, catalytic converter through the combustible mixture number is even smaller, so it can not be achieved for a long time working temperature. While in motion, due to the larger amount of fuel injection, catalytic converters can be 2-3km within the normal operating temperature quickly rose to not only extend the life of the conversion of pollutants in the exhaust also significantly increased. There is also a reason for moving warm than warm idle speed to consume a lot of fuel.
