Can Harvard 1.5T turbocharger breathe?

First of all, understand the in-cylinder direct injection turbocharged engine:

Direct injection turbocharged engine: The fuel is supplied by the two-stage oil pump driven by the engine, and the fuel temperature in all oil pumps and high-pressure rails is high, which is easy to produce air resistance!

All direct injection turbocharged engines are more prone to air resistance than traditional multi-point injection vehicles. In the traditional multi-point injection, the oil pump directly supplies oil to the fuel rail, the relative temperature of the fuel rail is low, the fuel has a loop, and the probability of air resistance is almost zero. Single loop-free fuel rail is still prone to gas resistance.

Direct-injection turbocharged engine: The high-pressure injector (nozzle) directly injects fuel into the combustion chamber, so if the gas burns, not to mention the combustion temperature of the gas, it absorbs less heat. The most important thing is that the nozzle does not work when the gas burns, and the in-cylinder combustion is easy to bet that the direct injection in the cylinder is blocked faster and more directly.

First of all, the direct injection turbocharged engine can't breathe, because the direct injection vehicle burns gas at high temperature, and the supercharger runs at high speed, so it is easier to gamble in the injector in the cylinder room after the fuel is burned. The disassembly and inspection of the plug of the direct injection injector can cost as little as several thousand yuan, and the replacement needs tens of thousands of yuan! So the money you saved is not enough for maintenance. (If a car is short of a few liters of oil, it will use a few square meters of oil. For example, in 5 yuan, 7 yuan, it can only give less than a third, and it will also use gasoline when the temperature is low!

In-cylinder direct injection turbocharged gasoline engine-refitting dual-fuel control system (combustible methanol, methanol gasoline, gasoline)-dual-fuel methanol gasoline vehicle.

It must be modified and used under the installation and guidance of the company's technicians or the company's trained technicians!

The following are the matters needing attention about methanol and methanol vehicles and the problem of changing automobile gas:

Do you know that unleaded gasoline, whether it is No.93, No.97 or No.90 gasoline, or ethanol gasoline, methanol gasoline or other new energy fuels such as alcohols, oils, biofuels, alcohol-based fuels and hydrocarbons, all contain methanol or ethanol? It's just different in content. As long as it contains methanol and ethanol, there are special requirements for pumps, oil level meters and fuel filters. And the original car is relatively durable, so there is no need to replace special accessories. Don't wait until there are two problems halfway! Simple modification: the pump is broken, the pressure limiting valve of the injector is blocked, the fuel gauge is broken, the power is gradually reduced, and the fuel consumption is gradually increased. Featured products: dual-fuel control of smart car, squirrel-cage frequency conversion fuel pump, non-contact magnetic induction liquid level device, special filter cloth, single fuel tank, double pumps and double insurance protection! The van was overhauled when it was replaced with 30,000-40,000 yuan. Now the state forces three guarantees, and no one dares to push the market! When the gas intake of automobile natural gas tank exceeds 15%, it is very explosive. 1' s hot car runs less, especially in winter, when the car is neither hot nor burning, you should carry a big jar before the peace talks at your destination.

Replace natural gas: drill the intake pipe, install compressed gas tank according to the charging valve ..., which is low in power, often blocks the oil nozzle, has high requirements for high-voltage lines and spark plugs, is seriously damaged, and has small displacement, so it is difficult for the car to run normally, and it is dangerous to leak gas when encountering sparks, and the gas tank intake is easy to explode. Ventilation is only a way of filling gas tanks, so many areas have begun to ban it or individuals have banned it.

Cars burn a few liters of oil, a few square meters of gas, about 7 yuan oil, about 5 yuan gas, saving about 30%, low power, danger, inconvenient refueling and other shortcomings!

As long as it is an EFI gasoline vehicle, it can be changed into intelligent dual fuel (3 ~ 12 cylinders can be used)! Or a car burning natural gas can burn methanol, (direct injection in the cylinder is to be determined _ the company or its technicians need to modify it) The dual-fuel control system of Shanjie smart car: saving fuel cost 1.5 (according to local traffic conditions), which is safer, more powerful and more convenient than burning natural gas!

Recommended double fuel tanks: (intelligent switching control or manual switching control), pure methanol can be burned all year round, GCM 100, double fuel tanks and double oil circuits.

Single fuel tank: there is no need to increase the fuel tank, and double pumps and double oil supply guarantee are recommended (squirrel-cage variable frequency fuel pump and original vehicle pump guarantee oil circuit without worry).

Unprofessional modification is bound to worry about bad pumps, oil meters and nozzles!

It's just different in content. As long as it contains methanol and ethanol, there are special requirements for pumps, oil level meters and fuel filters. And the original car is relatively durable, so there is no need to replace special accessories. Don't wait until there are two problems halfway! Otherwise, the pump will be broken, the pressure limiting valve of the injector will be blocked, the fuel gauge will be broken, the power will gradually decrease, and the fuel consumption will gradually increase. Specialty: wisdom

Double fuel control, squirrel-cage frequency conversion fuel pump, non-contact magnetic induction liquid level device, special filter cloth, single fuel tank and double pumps, which can be protected!

Traditional oil pump: ordinary oil pump, whether imported or made in China, is a DC brush pump. After methanol is electrified, carbon brush and lead are seriously oxidized (the conductivity of methanol is different from that of gasoline). The original car pump was relatively good (the original car pump ranged from several hundred yuan to several thousand yuan), but it broke down in less than a week.

Squirrel-cage frequency conversion brushless fuel pump: Squirrel-cage structure, to avoid carbon brush and lead contact with fuel oxidation damage, squirrel-cage motor has good startability, good power, good stability and durability, and maintenance-free; The frequency converter has high power and low calorific value, which is suitable for the automobile environment and ensures the reliable operation of the oil pump. The service life of the frequency converter can exceed the service life of the automobile. Meet the pressure and flow of various vehicles, with good fatigue resistance, good starting performance and strong anti-blocking ability.

Traditional level gauge: Ordinary level gauge is a sliding contact level gauge designed for gasoline. The conductivity of methanol is different from that of gasoline. After the sliding contact is electrified and oxidized, the resistance is inaccurate and the floating is appropriate.

Methanol, etc. The traditional oil level gauge is broken, not the oil gauge. (Medium-to-high-end cars are relatively durable in sliding contact with the liquid level. )

Non-contact magnetic induction level gauge: magnetic induction non-contact contact with fuel, avoiding the shortcomings of traditional level gauge.

Modification technology of methanol vehicle;

1. Locate the fuel injector (fuel injector). If filling is affected, hood, intake manifold, etc. Must be removed, which will affect the working parts.

2. Check the circuit control of the original fuel injector (high pressure fuel injector)! This is the preliminary work of technicians!

3. Only install dual fuel control system-processor! To control the signal of the original vehicle, the computer of the original vehicle has an amplification mode of 1.8 times to/kloc-0 times from -20 degrees to 20 degrees, and the methanol controller must have methanol from 20 degrees to a temperature suitable for methanol combustion.

4. Install the controller and go to the cab! And find the car control line! Installing negative wire

5. Install sensors (sensors must be installed independently to prevent conflicts with the original vehicle system), controllers and wiring!

6. Test run to see if it is normal. If it is normal, arrange the circuit with high-temperature resistant wire harness and bushing, because the car is most afraid of the problem of circuit oil circuit, and do a good job of preventing contact with the high temperature and friction of the exhaust system. The line adopts a high-temperature resistant line with a higher grade than the original car, which has a sense of casing.

7. Adjust the controller to find a mode suitable for this vehicle, and ensure good power after hot start, good cold start effect and good low-temperature power.

8. Slope test. The slope is above high speed 100, which requires power.

9, hide the controller, outsiders can't see the modified vehicle!

10, dual mode, if methanol mode is less methanol, intelligent control. If you burn gasoline, enter the gasoline mode and control it with the original car signal.
