Engine control system and engine control method

Abstract

The invention belongs to the technical field of energy saving and emission reduction of automobile engines, and discloses an engine control system and an engine control method. The engine control system includes: interconnected oil pan, oil pump, oil cooler, oil filter and oil insulation box, an oil heating device is arranged in the oil insulation box, and the oil insulation box is a hemispherical structure; interconnected The engine, water pump, radiator and cooling water insulation box are equipped with a cooling water heating device in the cooling water insulation box, and an arc-shaped accommodation groove is arranged on the cooling water insulation box. The arc-shaped accommodation groove is used to accommodate the oil insulation box. A gap is sealed between the oil insulation box and the cooling water insulation box; the medium collector is used to accommodate the heat transfer medium and can selectively fill the gap with the heat transfer medium for heat transfer between the cooling water insulation box and the oil insulation box and isolated. The engine control system increases the temperature of engine oil and cooling water and shortens the start-up time to meet the needs of energy saving.

Description

technical field [0001] The invention relates to the technical field of energy saving and emission reduction of automobile engines, in particular to an engine control system and an engine control method. Background technique [0002] As the public pays more and more attention to issues such as emissions and fuel consumption, energy conservation and emission reduction is the primary goal of automobile development. In the actual operation of the engine, when the engine is ignited, the cold start process of the cooling water and engine oil rising from a low temperature to a normal temperature lasts for a long time, especially in cold conditions, which directly leads to an increase in the fuel consumption rate of the engine and harmful The increase in pollutant emissions does not meet the requirements of energy conservation and environmental protection in today's society. [0003] The existing technology mainly realizes the energy saving and environmental protection of the autom...

AI Technical Summary

Problems solved by technology

The existing method has the following defects. First, the cooling water cycle and the engine oil cycle are independent, and one cycle cannot heat or cool the other cycle. There is a problem of energy waste, and in the cold start process, the temperature rise of the cooling water and engine oil The speed is slow, which is not conducive to the needs of energy saving and environmental protection; second, the existing control method is only suitable for a period of time after the engine is started, and it is not fully prepared before the engine is started, and it is in the normal driving state or driving It loses its function in a high temperature environment, resulting in a relatively narrow working range, which makes it difficult to meet the diverse needs of users
