Maximum speed over 160KM / H in the Alto, 0 ~ 100KM / H acceleration time of less than nine seconds of the Jetta, so a significant performance boost but the engine does not require any changes to the mechanical systems, engine control system modification to maximize the potential of the machine, and without changing the machine displacement and compression ratio, how? Attractive enough, right? Related Reading: How to extend the life of the engine valve train Modified turbo engine intake system introduced |
The heart of the automobile engine, the car Power Performance is basically determined by the engine's performance, expanding bore, changing compression ratio, turbocharger installation, modification of the common owners of these is too complicated, and there are certain risks, they might will cost down the machine, The ignition, spray and into the exhaust system by the modification done on the much simpler, and if the result is not satisfactory, you can easily change back, the following three aspects marketplace I speak from the engine control system modification.
1, increased ignition energy. Since most vehicles are no points with a high voltage electrical ignition system, ignition coil output voltage are above 100KV, the voltage used to ignite the mixture is more than sufficient, because the loss of high voltage and spark a large part of game energy, the actual voltage for the ignition only 20 ~ 50KV, therefore the main modification is to reduce the ignition.
Second, increase the fuel injection quantity. Addition to a handful of direct injection gasoline engine with the fuel supply cylinder mode, almost all of the gasoline engine is used in fuel injection intake manifold ways, it is in the engine fuel pipeline equipped with a fuel pressure regulator, the petrol pump output of about 7 ~ 10KG/CM2 fuel pressure dropped to 2KG/CM2 the following, and with the intake manifold pressure difference between the constant, the design conditions for most of the machine is applicable, but Cheng acceleration and maximum load conditions, which inevitably produces the problem of insufficient oil supply, there are two ways to solve this problem: First, manually change the mechanical fuel booster and because of additional fuel use electronic devices, mechanical fuel booster principle is simple, is to vacuum the oil pressure regulator removed, the regulator with a mechanical force to increase the oil pressure, and maintained at a constant value; the most comprehensive engine power lifting devices in recent years to the rise of a service called "oil supplementary" electronic device, it can now, according to the speed, engine speed and Throttle Opening at any time adjust the fuel injection quantity and ignition timing, which can play a good low-speed economy, but also in the high-speed and hard acceleration burst out when the startling power.
3, increasing air flow rate and change the vertical. If the air flow rate is not enough, the engine combustion mixture will not achieve the best combustion conditions, increase the gas into the well to change, now on the market generally, for adding a black mushroom head on it; improved exhaust system, are now generally car exhaust muffler pipe After a lot of corners, the exhaust will be not very smooth, into straight rows, can change places in general, increased intake, exhaust and smooth, and the power launched will be a lot of upgrading.
Department of energy loss, replacement of high-voltage lines and spark competition can effectively do that.
