Something about the maxidas ds708 neutral

Soley by mechanical means because the  maxidas ds708   carburetor passive work, regardless of the transmission is in neutral, the forward gear or reverse gear, as long as there is a gas, there will be a corresponding gasoline is sucked to participate in the combustion. Even if the driver release the throttle slide in the vehicle at high speed with a stopper under the coasting state, the engine still produce sufficiently low pressure in the intake stroke, resulting in gasoline was large suction the carburetor chamber, resulting in unnecessary fuel consumption. Hanging into neutral, the engine just keep idling and low engine speed, fuel consumption will naturally reduce the neutral slide carburetor vintage car, does have some fuel efficiency. So many drivers believe in "neutral gear and fuel-efficient" does have its reasons, but this is already more than ten years ago things.
Although now more and more passenger cars equipped with automatic transmission, but there are still many drivers continuation of many years handed down old driving habits, driving the new models, either manual  volvo vida dice  transmission or automatic transmission, to take the neutral slide the driver is still a lot of people, then we look at from a technical point of view, the car now, this experience can apply?
Sales of passenger cars used in all electronic fuel injection, computer control valve to control the turn-on time of the injectors and the fuel injection timing and fuel injection quantity correction independently of each cylinder based on a variety of sensors to achieve a more accurate control effect. The engine control computer (ECU) has a "slow off the oil" program, in high-speed driving, the driver release the throttle vehicles to enter with sliding block, fuel injectors to stop oil supply to the cylinder.
The vehicle slows to a certain extent, in order to ensure that the engine will not be a car "drag" turn off the engine computer will re-fuel supply to maintain the engine to maintain a certain power output. Under normal circumstances, the ordinary civilian cars in the speed of 40km / h or more to enter the coasting state with the stopper, the engine control computer will be reduced or even completely cut off the fuel supply, thereby reducing the fuel consumption in the coasting state. Control range and mb star c3   speed in the flat or downhill surface can be achieved in the case of zero fuel consumption or low fuel consumption glide long distances.
