Embodiment Construction

[0024] figure 1 Shown is one embodiment of the invention, a gasoline engine having four cylinders, each cylinder having a volume of 0.25 liters, for a total engine volume of 1 liter.

[0025] exist figure 1 In the shown embodiment, the upper opening of the cylinder body 1 is sealed by the cylinder head 3, and the fuel injection nozzle 5 of the fuel injection device is arranged in the center of the cylinder head 3, and the high-pressure water spray device is also arranged on the cylinder head 3 next to the fuel injection nozzle 5. The water nozzle 6, the opening and closing of the water spraying device and the adjustment of the water spray volume are controlled by the control device, which also controls the opening and closing of the fuel injection device and the adjustment of the fuel injection volume. The air port 8 is opened on the cylinder head 3; the lower port of the cylinder body 1 is connected to the crankcase 4, and the crankcase 4 is provided with a crank connecting ...

Abstract

The invention discloses a high-efficiency internal-combustion engine. The engine comprises a cylinder body, an air inlet device, a fuel injection device and a piston, wherein the air inlet device and the fuel injection device, which are communicated with a cavity of the cylinder body, are arranged on the cylinder body; and the piston does reciprocating motion in the cylinder body. The high-efficiency internal-combustion engine is characterized by also at least comprising a water injection device and a control device; the water injection device can atomize water and import the atomized water into the cavity of the cylinder body; and the control device controls the open and close of the water injection device, adjusts the water injection quantity, and controls the water injection device to spray the atomized water when the piston does inhaling movement. By adopting the measure of spraying the atomized water to a combustion chamber for cooling, the high-efficiency internal-combustion engine can effectively prevent the early deflagration, the compression ratio of the engine is increased and the atomized water is increased, so the power output of the engine is improved.

Description

(1) Technical field: [0001] The invention relates to an engine, in particular to a high-efficiency internal combustion engine. (two) background technology: [0002] The main body of the internal combustion engine is a cylinder block, the upper opening of the cylinder block is covered by a cylinder head, and a piston is arranged in the cylinder body, and the piston reciprocates between the top dead center of motion and the bottom dead center of motion in the cylinder body. [0003] The reciprocating motion of the piston is divided into four processes: intake, compression, explosion work and exhaust: [0004] 1. Air intake (i.e. inhalation). When the piston moves downward from the top dead center, the intake port is opened and the exhaust port is closed. During the downward movement of the piston from the top dead center to the bottom dead center, the valve of the intake port is in an open state, and the valve of the exhaust port is in a closed state. When the piston moves ...
