A kind of automobile engine cylinder-body manufacturing process, by the combustion characteristics research of different automobile engines, three-dimensional simulation calculating is carried out to engine block structure, gradual perfection manufacturing process, special main parts size-the gray iron of energy saving environment protection engine is produced, the following aspects is mainly reflected in：
(1) because the structural parameters of cylinder head air inlet passage have a direct impact to its circulation and swirl ratio, and circulation and swirl ratio are the key factors for affecting engine combustion process, burning is more abundant, not only lose less, the power of electromotor also can be improved, and making the exhaust emissions of electromotor lower, the pollution to environment is less.
(2) due to the structure and size of engine chamber, engine power performance and discharge are had a significant impact, by using Three-dimensional Combustion analysis software, the simulation for carrying out different engine combustion processes is calculated.
(3) because the production process resource and consumption of cylinder body are larger, after implementing new technology, the production process for making cylinder body reaches the purpose of energy-conserving and environment-protective.Superseded low production efficiency, the equipment of high energy consumption all using high degree of automation and low power consuming equipment, and designs continuous cycle production process flow process, reduces consumption and reaches energy-conservation purpose.Product shape size and structure design follow the principle of high-mechanical property, and resource consumption is reduced as far as possible.
In above-mentioned technique, need to be related to following main raw and auxiliary material supply
（1）The pig iron：Gray iron carries out melting by raw material of the pig iron, then moulding by casting.The main component of the pig iron is C, Si, Mn, S, P, according to the different trades mark of product material from the pig iron containing heterogeneity.
（2）Steel scrap：Gray iron carries out melting with steel scrap and the pig iron as primary raw material, then moulding by casting.Product adds steel scrap to increase the plasticity of prolonging of product, reduces product brittle failure.Meet environmental requirement using waste material simultaneously.
（3）Precoated sand：Precoated sand is processed with lithotome, and with the characteristics of intensity height, good permeability, the visual quality of casting is easily ensured after sintering, non-corrosiveness gas during sintering is harmless.

The beneficial effect of the invention is：Energy-conserving and environment-protective special engine cylinder body not only meets the needs of fuel automobile engine, and meets the needs of many live steam car engines；Simultaneously the product can not only improve the power of electromotor, reducing energy consumption.
Specific embodiment
The specific embodiment of the present invention is described with reference to embodiment, to be better understood from the present invention.
Embodiment
1
Automobile engine cylinder-body manufacturing process in the present embodiment, by the combustion characteristics research of different automobile engines, three-dimensional simulation calculating is carried out to engine block structure, gradual perfection manufacturing process, special main parts size-the gray iron of energy saving environment protection engine is produced, its technical advance is mainly reflected in the following aspects：
(1) because the structural parameters of cylinder head air inlet passage have a direct impact to its circulation and swirl ratio, and circulation and swirl ratio are the key factors for affecting engine combustion process, burning is more abundant, not only lose less, the power of electromotor also can be improved, and making the exhaust emissions of electromotor lower, the pollution to environment is less.Because different circulations is different with swirl ratio, designed using three-dimensional simulation, the air intake duct of different engine cylinder covers is separately designed, be finally reached the purpose of automobile engine energy-conserving and environment-protective.
(2) due to the structure and size of engine chamber, engine power performance and discharge are had a significant impact, by using Three-dimensional Combustion analysis software FAIR, the simulation for carrying out different engine combustion processes is calculated, analyze its combustion characteristics, the combustion chamber design for taking into account dynamic property, economy, discharge index and reliability is obtained by numerical computations and experimental study so as to which engine cylinder-body reaches the purpose of energy-conserving and environment-protective.
(3) implement to be made after technological transformation the production process of cylinder body to reach the purpose of energy-conserving and environment-protective because the production process resource and consumption of cylinder body are larger.Superseded low production efficiency, the equipment of high energy consumption all using high degree of automation and low power consuming equipment, and designs continuous cycle production process flow process, reduces consumption and reaches energy-conservation purpose.Product shape size and structure design follow the principle of high-mechanical property, and resource consumption is reduced as far as possible, reach the purpose for economizing on resources.Cylinder cap production adopts ferrum precoated sand casting technique, increases precoated sand reclaiming equipment, and the consumption of precoated sand had both greatly reduced, and the pollution of antiquated sand is reduced again.Because cylinder body is using the production technology of cold-hardening resin sand, recovery and reusing and recycling is carried out to used resin sand by resin sand reclaiming equipment, greatly reduce the consumption of resin sand, also reduce pollution of the antiquated sand to environment produced by traditional processing technology.
