Automotive engine boost and tail gas purification technology and combination

Abstract

The invention discloses an automotive engine booster and a tail gas purifier technology; and the two are combined as a whole, so that the effects of oil saving and emission reduction of an automotive engine are the best, and the protection of natural environment atmosphere is facilitated. Two times of dual boost are performed for air (2) by a double-turbine air pump (4) mounted in an engine air filter (1) to form a boost eddy current (6); the boost eddy current is adjusted through a throttle valve (8), and enters an engine cylinder (12) for compressing to improve a relative compression ratio of the engine; and after mixed gas is combusted, the power of the engine is increased, and fuel is relatively decreased. Discharged tail gas pollutants (26, 24) enter tail gas purifiers (42, 18, 17, 16) for purifying; and the purifying treatment adopts two modes of an alkali liquid (19) absorption method and a solid (18, 16) absorption method. Purified gas (14) is exhausted to the atmosphere through a purifying exhaust pipe (15). A synchronous controller assembly (38) can keep synchronous implementation of the engine boost and the tail gas purification. A tail gas boost air pump (42) is mounted in a tail gas purifier air inlet pipe (23) for performing the gas boost for the tail gas pollutants. A vehicle-mounted accumulator (40) provides electric energy to the synchronous controller assembly.

Description

technical field [0001] The invention belongs to the fuel-saving and emission-reducing technology of automobile engines, and specifically relates to a supercharger and an off-machine purification treatment technology for exhaust gas of the engine. The best effect, which is beneficial to reduce fuel consumption and protect the natural atmospheric environment. Background technique [0002] Theory and practice show that: without changing the type of fuel, increasing the air volume of the engine can significantly improve the power performance of the engine and reduce fuel consumption and pollutant gas emissions. [0003] Traditional supercharging and exhaust gas turbocharging technologies, mechanical supercharging consumes a lot of engine power, and exhaust gas turbocharging has the disadvantages of low-speed supercharging and supercharging hysteresis, and the production costs of the two supercharging devices are expensive. In particular, the post-maintenance cost of exhaust gas...
