Abstract: The object of the invention is a multi-purpose internal combustion engine, which is a 4-stroke engine with or without a turbocharger with a spark ignition or compression ignition, which can work interchangeably in 2 different ways: 1. - normal operation, by using all cylinders as shown in Fig. 1A and 6A; 2.- in an economical way, when some of its cylinders are switched off and with expansion of the exhaust gases in these cylinders from the cylinders working as in Fig. lB, 2C and 2D as well as 6B, 7C and 7D. The exhaust gas pressure in the cylinders at the time of opening the exhaust valves is even up to 6 bar above the atmospheric pressure. This engine differs from a normal engine mainly by the construction of the head and timing. When the vehicle gains speed and when the demand for power is much smaller, the engine control unit switches off the operation in some of its cylinders and changes the control of the valves. Then, the engine works in an economical way. The expected increase in efficiency is up to 15% compared with the engine in which the power is switched off only in some of the working cylinders.

Abstract translation: 本发明的目的是一种多用途内燃机，其是具有或不具有火花点火或压缩点火的涡轮增压器的四冲程发动机，其可以以两种不同的方式互换工作： 1.正常操作，通过使用所有气缸，如图1所示。 1A和6A; 2.以经济的方式，当其一些汽缸关闭并且这些气缸中的废气从气缸中膨胀时，其工作方式如图1所示。 1B，2C和2D以及6B，7C和7D。 打开排气阀时气缸中的废气压力甚至高于大气压力6巴。 这种发动机与普通发动机的不同之处主要是由于头部的构造和时间。 当车辆获得速度并且当功率需求小得多时，发动机控制单元关闭其一些气缸中的操作并改变阀门的控制。 然后，发动机以经济的方式工作。 与仅在一些工作气缸中关闭电源的发动机相比，预期的效率提高高达15％。
