Description

engine heating system

technical field

The utility model relates to an engine heating system.

Background technique

Engines (such as piston engines), due to the characteristics of the product itself, are particularly difficult to start for the first time or vibrate when the temperature is low, especially in the cold north.

The root cause of engine (such as piston engine) difficulty in starting for the first time or jitter is poor combustion in the cylinder and insufficient power provided by the engine, which are specifically reflected in the following aspects: 1. Low ignition energy; 2. Increased ignition gap of the spark plug; 3. Improper oil-air mixing ratio; 4. Carbon deposits on valves and intakes; 5. High viscosity of lubricating oil; 6. Other factors such as air and oil that do not meet the requirements.

For engines used in aircraft (such as aviation piston engines), it is very common to tremble or fail to start when cold starts, and it is necessary to climb the oars many times, start repeatedly, and warm up the car for a long time after starting. It wears a lot, wastes fuel, and is not conducive to instant flight.

Detailed ways

The embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, but the utility model can be implemented in various ways defined and covered by the claims.

Fig. 1 is a schematic diagram of the engine warming system according to the present invention in operation. As shown in Figure 1, the engine heating system includes a hot air blower 11 and a flexible wind cover 12 connected to the air outlet 116 of the hot air blower 11, and the flexible wind cover 12 is used to be sleeved on the engine 20 to be preheated, It is unfolded when in use and folded when not in use.

Before the engine is started, it is heated for 3 to 5 minutes, so that its various parts are heated to a certain temperature, and it enters the working state in advance. In this way, the one-time starting success rate of the engine can be improved. Compared with the prior art, the engine does not need to be warmed up for a long time, the fuel consumption is reduced, and the reliability of instant flight is improved. In the test run of an aviation piston engine at an airport, the success rate of the engine starting at one time can reach 95%, and the jitter phenomenon of the engine at the first start is greatly reduced.

Preferably, the flexible windshield 12 is a cloth bag, which is trumpet-shaped when fully opened, and has a tightenable sleeve 121, for example, an elastic belt is sewn on the sleeve 121, and/or a drawstring is provided on the sleeve. It should be pointed out that in other occasions, the flexible windshield is an assembled structure, for example, temporarily assembled by several pieces of cloth through zippers or micro-claw gluing buttons. By arranging the flexible air cover 12, the hot air can be utilized more effectively, waste can be reduced, and the heating efficiency of the engine can be improved at the same time.
