Abstract

The invention provides a sliding driving control method and device during vehicle running. The engine equipped with the vehicle is equipped with a set of control valve device, which can randomly control the intake valve or the exhaust valve to be in the open state at any time. Out of gear, the program control stops the fuel supply to the engine, and the engine intake valve or exhaust valve is in a normally open state to control the vehicle to coast, which reduces the running resistance of the engine when the vehicle is coasting and improves the fuel-saving effect when the vehicle is coasting.

Description

Slide driving control method and device during vehicle running

technical field

The present invention relates to the technical field of vehicles.

Background technique

In order to reduce the fuel consumption during the driving of the vehicle, people use the inertia of the vehicle to stop fuel supply to the engine and make the vehicle slide for a certain distance to reduce fuel consumption. There are two ways to drive a vehicle coasting: the first is to disengage the gear, stop the fuel supply of the internal combustion engine, and drive the vehicle to coast. The second is to not disengage, the internal combustion engine to stop fuel supply, and to drive the vehicle to coast. Adopting the first vehicle coasting driving method reduces the running resistance of the internal combustion engine and improves the fuel-saving effect compared with the second vehicle coasting driving method. However, the first type of vehicle coasting has potential safety hazards, and traffic regulations do not allow vehicles to adopt this driving method during driving, but allow the second type of vehicle coasting driving method. At present, the second vehicle coasting driving method has been designed in the control of vehicle running.

SUMMARY OF THE INVENTION

In order to overcome the running resistance of the internal combustion engine existing in the sliding of the vehicle such as the vehicle does not disengage and the internal combustion engine stops fuel supply, and further improves the fuel-saving effect of the vehicle sliding, the present invention proposes a sliding driving control method and device during the driving process of the vehicle, which is characterized by: The engine equipped with the vehicle is equipped with a set of control valve device, which can randomly control the intake valve or exhaust valve to be open at any time. The exhaust valve is normally open to control the vehicle coasting. According to the actual test, the valve is normally open when the engine is running, which reduces the upward resistance of the piston, and the running resistance of the engine is reduced by 62%. The use of this vehicle coasting driving control method improves the fuel-saving effect of the vehicle when coasting.

specific implementation measures

Example 1

In Figure 1, 1 electromagnet installation pressure plate, 2 electromagnet, 3 electromagnet moving iron core, 4 rocker arm, 5 valve. Set 1 electromagnet installation pressure plate above the engine 4 rocker arm, 1 electromagnet installation pressure plate to fix 2 electromagnets, when the engine is running normally, the 3 electromagnet moving iron core does not extend, when the vehicle is sliding, the control Program command 3 The electromagnet moving iron core stretches out when the 5th valve of the engine goes down and is located between the 4th rocker arm and the 5th valve. The 5th valve cannot reach the closed position and is in a normally open state, reducing the upward resistance of the piston, thereby reducing the running resistance of the engine , to improve the fuel-saving effect of vehicle coasting. The device can randomly control the engine intake valve or exhaust valve to be open at any time.

Embodiment 2

In Figure 2, 6 hydraulic cylinders, 7 pistons, 4 rocker arms, 5 valves. There are 6 hydraulic cylinders above the rocker arm of the engine 4. When the engine is running normally, the 7 pistons do not extend. When the vehicle is coasting, it does not disengage. The control program stops the engine oil supply, and the control program commands 7 of the 6 hydraulic cylinders. The piston is extended, and the 4 rocker arm is directly pressed down, so that the 5 valve is pressed down to a size that does not affect the normal operation of the piston, so that the 5 valve cannot reach the closed position and is in a normally open state, reducing the upward resistance of the piston, thereby reducing the running resistance of the engine. Improve the fuel-saving effect of vehicle coasting. The device can randomly control the engine intake valve or exhaust valve to be open at any time.

Embodiment 3

The engine equipped with the vehicle is equipped with a set of control valve device, in which the power to press down the 4 rocker arm and the 5 valve is the cylinder, and the working process is the same as that of the second embodiment.

Due to the adoption of the above technical measures, the fuel-saving effect when the vehicle is coasting is improved.
