Abstract
A V-type supercharged diesel engine exhaust system consists of two separate exhaust pipes (2) and (3) and superchargers (4) and (5) corresponding to each line of cylinders. The two exhaust pipes (2) and (3) are communicated through a compensation pipe (6). Air flows in the exhaust pipes (2) and (3) are mutually independent and also mutually compensate; pressure of the system is gradually stabilized; balance of work of each cylinder is greatly improved; therefore, thermal performance of a diesel engine have been significantly enhanced.
Description
Technical field
The utility model belongs to Diesel Engine Technique Field, relates in particular to a kind of novel V-type supercharged diesel engine vent systems
Background technique
Usually the corresponding separately outlet pipe independently of two row cylinders of V-type supercharged diesel engine, and in order to improve the followability of off design performance and supercharging parameter, choosing of outlet pipe diameter is always less relatively.But improve with the diesel engine strengthening degree, the pressure wave that forms in the outlet pipe can form the inlet and outlet process of individual cylinder and disturb, thereby cause the burn deterioration of these cylinders and delivery temperature to raise, operational differences between each cylinder increases, when select the outlet pipe sectional area less than the cylinder sectional area 40% the time, this interference is particularly evident, brings very adverse influence for the Economy and the reliability of diesel engine.Prior art adopts the way of optimizing circulating fuel injection quantity and injection timing at individual cylinder, though can address the above problem to a certain extent,, this is a cost with each cylinder working imbalance.Diesel engine is at different rotating speeds, the cylinder difference of being disturbed under the different operating modes, thereby in fact the effect of this kind method is unsatisfactory.
Summary of the invention
The purpose of this utility model will overcome the deficiency of above-mentioned prior art exactly, and a kind of balanced exhaust pressure is provided, and reduces the novel V-type supercharged diesel engine vent systems that exhaust pressure wave disturbs the cylinder inlet and outlet.
The purpose of this utility model is achieved in that a kind of V-type supercharged diesel engine vent systems, by the every row cylinder of correspondence separately independently two outlet pipes (2), (3) and pressurized machine (4), (5) constitute, it is characterized in that with the afterbody connection of a compensation conduit (6) two outlet pipes (2), (3).
Adopt scheme of the present utility model, gas flow in the outlet pipe is not only relatively independent but also compensate mutually, the pressure level-off of system, each cylinder operation balance is improved greatly, thereby makes the performance of aspects such as air mass flow, volumetric efficiency, coefficient of residual gas, cylinder indicated work, cylinder maximum combustion pressure and cylinder delivery temperature all obtain significant raising.
Description of drawings
Fig. 1 is the utility model embodiment's a principle schematic.
Embodiment
Referring to Fig. 1, on V-type supercharged diesel engine (1), corresponding every row cylinder is provided with separately independently two outlet pipes (2), (3) and pressurized machine (4), (5), and compensation conduit (6) interconnects them at the afterbody of two outlet pipes.When forming pressure pulse in the outlet pipe, then form a low pressure in another root pipe, the compensation conduit (6) that two outlet pipes (2), (3) connection are got up can be so that there be an exhaust pipe volume of pressure pulse to extend to another root outlet pipe relatively.The interior pressure pulse of this root outlet pipe this moment will be alleviated, and the low pressure in another root outlet pipe will be compensated recovery.
Claims (1)
1, a kind of V-type supercharged diesel engine vent systems, by the every row cylinder of correspondence separately independently two outlet pipes (2), (3) and pressurized machine (4), (5) constitute, it is characterized in that with the afterbody connection of a compensation conduit (6) two outlet pipes (2), (3).
