2 computer-controlled variable

Variable refers to a computer-controlled car equipped with three engine control unit, respectively, in accordance low engine speeds, normal and maximum power output of the three kinds of operating state design program, and in accordance with the actual needs, to switch the corresponding control unit work. If these three kinds of operating modes using a control unit to achieve, program control will significantly increase the difficulty, and when the control unit fails, the car will not run, so from the perspective of safe, reliable and easy to implement point of view, the use of design 3 engine control unit is more reasonable.
Third, strengthen the conservation of the car,(vw turbocharger)
1. improve vehicle maintenance technical level
Timely and correct maintenance will extend the life of the car, is to ensure traffic safety and vehicle dynamics play an important part in nature. Maintenance companies in the automotive maintenance process can take the following measures to ensure the quality of services and to improve the technical level of service and maintenance personnel.(saab turbo)
(A) at the time of vehicle maintenance, in order to avoid missing items, maintenance companies should try to use "double action" law and require maintenance personnel to ensure the quality of maintenance are in line with each of the requirements to meet the technical specifications.
(2) for regular maintenance technician training, discuss and resolve work problems. Meanwhile explain some new models, new technical knowledge, so as to improve vehicle maintenance personnel skill level purposes.
(3) to be used for replacement parts meet the standards of original parts or accessories regular manufacturers to ensure its performance and life expectancy of the original requirements.
(4) to guide the user to grasp the most basic car maintenance knowledge to enable them to carry out regular inspections in accordance with the relevant regulations.
2 Use high-quality fuels and lubricants(performance parts)
(1) To select clean, consistent quality fuel quality requirements. Dirty fuel will cause the oil to poor, does not meet the quality requirements of fuel the engine will produce coke, and even knock or circumstances appear corroded parts. Only select the correct label, clean and high quality fuel to make the power of the car full.
(2) improve the quality lubricants. Lubricants, including engine oil, gear oil and grease, and other products, use of lubricants to meet API standards. Further improvement of the quality assurance of the lubricating oil which does not deteriorate at high temperature, to prevent the gum, coke and an acid generating substance can also serve to increase the oil film thickness to reduce wear between moving parts, mechanical protection against corrosion increase engine power, to reduce noise, and extend the service life of mechanical action.
3 rational use of additives
(1) gasoline additive. Additives in gasoline can play remove coke, reduce fuel consumption, to avoid the car engine metal surface oxidation, corrosion prevention effect and the oil pipeline road system, clean oil passage.
(2) diesel fuel additives. Additive for diesel fuel, such as diesel fuel anti-coagulation agent can improve the low temperature fluidity of diesel fuel, diesel fuel at low temperature to prevent freezing.
(3) oil additives. After adding additives in the oil will help to improve starting performance; may prolong engine life, increase power; sealing between the piston and the cylinder increase, so will significantly increase cylinder pressure, so that the engine power has been improved.
(4) gear oil additive. Gear oil additive has the following effects: reduced mechanical energy loss during delivery, to a certain extent, reduce engine fuel consumption; improving film strength, improve resistance to extreme pressure performance gear oil, to avoid gluing surface gear, wear, plastic deformation, fatigue and fracture and other injuries.
(5) air-conditioning system additives. Additives for the air conditioning system, air conditioning system can reduce energy consumption, reduce friction and noise, odor removal, extended compressor filled with the oil of the life cycle and the system components.
