Formula car engine air intake system

Abstract

The invention discloses a formula car engine air intake system, which comprises an air filter, a throttle valve, a flow limiting opening, a diffusion tube, a resonant cavity, a variable air intake manifold and a manifold length regulator, wherein the inlet cone angle and the outlet cone angle of the flow limiting opening are respectively 14 degrees and 6 degrees, the outlet of the flow limiting opening is connected with the diffusion tube, the outlet of the diffusion tube is connected with the resonant cavity, the diffusion angle of the diffusion tube is 6 degrees, the length is 220mm, the resonant cavity is molded by an ABS material through upper and lower die separating and numerical control milling, the volume is 3L, and the internal part of the resonant cavity is equipped with the manifold length regulator. The working length of the air intake manifold is enabled to meet manifold characteristic requirements that the air intake manifold needs to be thin and long at a low speed and needs to be short and thick at a high speed of the engine through additionally arranging the manifold length regulator, the variable length of the air intake manifold can better utilize a resonant airintake effect of the engine in different speed ranges, the air intake efficiency is improved, and the overall performance of the variable air intake manifold is better than that of the traditional non-variable air intake manifold structure.

Description

technical field [0001] The invention relates to the field of formula racing cars, in particular to an engine intake system for formula racing cars. Background technique [0002] Formula racing is a racing car built with a common formula (rule restrictions). The racing car must be manufactured in accordance with the procedures stipulated in the vehicle technical rules formulated and issued by the International Automobile Federation, including car body structure, length and width, etc. Formula Student racing car is a kind of Formula racing car. It is a simplified version of Formula One car designed by a team of college students. It is required that the car has a high level of acceleration, braking, and handling, and it is stable and durable enough. A series of test items can be completed in the test. [0003] In the field of passenger cars, there are two commonly used engine air intake systems, fixed type and graded adjustable type (usually two-stage). The adjustable range s...

Problems solved by technology

At non-specific speeds, the air intake system has large air intake resistance and low air intake efficiency, resulting in a serious drop in engine output power and torque

There is a variable intake system design using telescopic baffles, which solves the optimization of the engine intake system at different speeds to a certain extent, but the air intake resistance of this scheme increases significantly when the baffles are involved in the work, which does not Conducive to the improvement of the air intake efficiency of the air intake system
