Abstract

The present invention relates to the technical field of a diesel engine, in particular to a method for cyclically stopping a cylinder of a V-shaped arrangement diesel engine, it is taken as an example that each cylinder is ignited once in turn when a crankshaft is rotated in a range of m degrees, let the number of cylinders be n, n/2 cylinders ignite during the first m/2 degree of a working cycle, and the other n/2 cylinders ignite in turn during the second m/2 degrees of the working cycle. For the method for cyclically stopping the cylinder of the V-shaped arrangement diesel engine of the present invention, in the working cycle of the normal four-stroke diesel engine, half of the cylinders stop working, thereby achieving effects of improving combustion, reducing fuel consumption, and avoiding a smoke exhaust pipe of a pressurizer from injecting fuel. During the idling operation of the diesel engine, a method of stopping a plurality of the cylinders to increase the fuel-injection volume of the single working cylinder is used to improve the control accuracy and atomization quality of the fuel injection of the single cylinder, improve combustion, reduce the fuel consumption, reduce emissions, and solve the problem of the fuel injection from the smoke exhaust pipe.

Description

Ail cylinders of a four-stroke multi-cylinder diesel engine ignite once in tum in every two révolutions of a crankshaft. For a diesel engine using a single-pump fuel System, the ratio of the amount of fuel injected by a nozzle of each cylinder during an idling operation to the amount of the fuel injected by the nozzle of each cylinder during a working condition at a rated power at a rated speed is about 1: 51000, due to a large range of a change in a fuel volume at high and low working conditions, a control accuracy of the nozzle is poor during the injection of a small fuel amount, further, due to a low fuel injection pressure and poor atomization during a low-speed operation, the fuel in the cylinder cannot be completely bumed after the diesel engine has been in an idling operation for a long time, and the accumulated fuel sprays out from a smoke exhaust pipe of a pressurizer, which pollutes an environment and wastes fuel. For a shunting locomotive, running time is long under idle conditions, and the problem of fuel injection from the smoke exhaust pipe often occurs.

In order to solve the problem of the fuel injection during the idling operation, a method of a single-row oil stopping is adopted, that is, for a four-stroke V-shaped cylinder arrangement diesel engine, the fuel supply of one row of cylinders is stopped during the idling operation, in order to maintain the rotation speed of the diesel engine, the single-cylinder fuel injection amount of the other row of the cylinders is doubled, the control accuracy of the fuel injection amount of each nozzle is correspondingly improved, and the atomization is improved, so that the fuel can be fully bumed in the cylinder of the diesel engine, and the problem of the fuel injection from the smoke exhaust pipe is avoided. However, this solution has the following disadvantages:

1. One row of the cylinders of the diesel engine works while the other row of the cylinders does not work, resulting in unbalanced operation of the diesel engine and increased vibration.

2. The cylinder on the working side wears more than the cylinder on the non-working side.
