Description

Axial flow aerodynamic force internal-combustion engine turbine air-admission pressure-booster

Technical field

The utility model belongs to internal combustion engine turbocharging technical field, relate in particular to a kind of without by external impetus, the structure that do not change automobile just can combustion motor realizes the pressurized machine of turbine air intake pressurized.

Background technique

At present, the turbosupercharger that motor car engine is used is both at home and abroad divided into two kinds substantially, comprises and need to consume external energy and not need to consume two kinds of external energies.The pressurized machine that need to consume external energy has mechanical type and electrodynamic type: mechanical turbine pressurized machine obtains power from engine output shaft, complex structure, and volume is larger, and price is high; Electric turbocharger is with the electric drive pressurized machine motor work of automobile itself, and working life is partially short.Do not need the pressurized machine that consumes external energy taking exhaust-gas turbocharger as main representative.Exhaust-gas turbocharger is taking the waste gas of motor discharge as power, and distinct disadvantage is response lag, and the floating axle that connects exhaust driven gas turbine and the air inlet turbine easy axis of at high temperature working; In addition, the design accuracy of exhaust gas turbine requires high, complex manufacturing technology, volume larger.In order to make up the defect of exhaust gas turbocharge, composite turbocharging system had both adopted exhaust-gas turbocharger, and while application machine drive-type turbosupercharger overcomes the retardation phenomenon of exhaust-gas turbocharger again, but manufacture cost and maintenance expenses are higher.

Above-mentioned turbosupercharger also has a common problem, while using above-mentioned turbosupercharger to reequip the old motor car engine of having dispatched from the factory, need to carry out some transformations to automobile local location structure or circuit etc., therefore these turbosupercharger, except new car prepackage, are promoted not by most of car owners are accepted by repacking.

How not change under the condition of vehicle structure, can make some old vehicle motors obtain a kind of axial flow aerodynamic turbine of turbo charged effect pressurized machine to have solved preferably the deficiency of above-mentioned turbosupercharger.Aerodynamic turbine pressurized machine does not need to consume external energy, only just can realize the high-speed rotary of turbine blade by the air-breathing power of internal-combustion engine then reach the object of supercharging, turbo charged effect just can play a role in the time that engine speed 1200 turns, to meet the demand of urban district low speed driving, and apparatus structure is simple, install additional conveniently, cost is low.

Summary of the invention

The utility model provides a kind of bilobed wheel axial flow aerodynamic turbine air-admission pressure-booster in order to solve deficiency of the prior art, simple in structure, assembly is few, without just realizing turbine air intake pressurized to motor car engine by external impetus, can directly be installed in the suction tude that motor car engine closure is connected with air filter, its Component material is common, there is good durability and safety reliability, not only can overcome the defect in above-mentioned background technology, and can solve turbine air intake pressurized apparatus and on old automobile, carry out popularization and application problem.
