How to Set a Car Carburetor

There are 3 screws on the carburetor which plays an important role to make the gasoline engine to be optimized. Here are 6 ways to tune the carburetor car.

1. Idle screw loosened up but the air conditioning is turned on. Tuning stops when the screw was no longer able to degrade engine RPM.

2. Screw RPM engine RPM down to about 500, or to not die.

3. Now mulaid ith idle set screw (mixture of air and gasoline). Turn the screw to the left until near death. Then back to the right until nearly died too. After that rotate slowly seeking the highest RPM. That's when we'll find the best mixture of gasoline and air.

4. After finding the best mix, now that the screw RPM to 700, 800, or 900 engine makers demand.

5. Now new menyetelah idle screw up AC. Turn on the AC, RPM certainly been reduced, down from the original. Now sets the idle screw up until it reaches the RPM, usually 900 or 1000.

6. Try AC is turned off, if the current idle RPM to the desired RPM

How Injection is Working

Functions and how the components of electronic gasoline fuel injection or EFI system consists of two main systems fuel systems, air induction systems.

a. Fuel System

Fuel system works to deliver fuel from the tank to the combustion chamber.

Fuel system components consist of:

1. Fuel Pumps

Serve fuel pump to deliver fuel from the tank to the injector. Digukanan fuel pump is an electric fuel pump.

2. Fuel Pulsation Damper

Fuel pulsastion serves as an absorber damper on the duct pressure changes due to the injection pressure. Fuel pressure in the intake manifold is maintained by a pressure regulator.

3. pressure Regulator

Pressure regulator controls the fuel pressure to the injector-injector. The amount of fuel injected is governed by a signal supplied to the injector so that the pressure must be kept on each of each injector. To get the right amount of spraying, the fuel pressure should be maintained approximately 2.55 kg/cm2.

4. injector

Injector nozzle is a multilayered work of electromagnetic controlled by the computer. Injector equipped with a heat insulator at the inlet or to the head close to the hole slinder income.

5. Cold Start injector

Cold start injector is used to supply materials at low engine temperatures. Injector is mounted in the center of the room air. Injector works only at the start when the cooling water temperature in that 220 celsius.

2011 Aston Martin DB9.

Aston Martin has released a 2011 minor facelift of the DB9 with package of improvements. It would probably take more than a few glances to notice the new styling changes which include a new front bumper, bright finish radiator grille, reshaped lower intake featuring bright hexagonal mesh, new headlight coverings, restyled sills, silver brake calipers, 20-spoke “diamond turned” alloy wheels and clear rear light lenses.

Besides the sleek sheetmetal, popularity of the DB9 stems from the 6.0-litre V12 engine that lives under that long hood. It comes with 470 hp, 600 Nm and lots of charisma. Power is fed to the rear wheels via a rear mid-mounted six-speed manual gearbox or an optional Touchtronic 2 six-speed auto.Prices start from £122,445 for the Coupe, while the Volante retails from £131,445.

Mazda Premacy launched in Japan with 2.0L.

The new smiley faced Mazda Premacy (known as the Mazda 5 here in Malaysia) is now officially on sale in Japan, with suggested retail prices of between 1,799,000 to 2,314,000 yen, including sales taxes. Not sure when Bermaz will be bringing it in as the new Mazda 5 but perhaps a few grey importers like Naza World will get to it first.

The Mazda Premacy is available with i-stop in Japan, which is Mazda’s unique idling stop system that can automatically stop and restart the engine nearly instantly to save fuel. The i-stop model grades (20S and 20E FWD) offer the highest fuel economy of any two-liter minivan in Japan, rated at 16.0 kilometers per liter (km/l) according to Japan’s 10-15 mode test cycle, while the same models with power sliding doors are rated at 15.0 km/l.

All FWD models of the Premacy in Japan are powered by a direct injection 2.0 liter engine making 150 PS at 6,200rpm and 186Nm of torque at 4,500rpm, mated to a 5-speed Activematic automatic transmission. The 4WD version uses a regular 2.0 liter DOHC engine mated to a 4-speed EC-AT automatic transmission.

Ferrari 612 Scaglietti.

The 612 Scaglietti is not a very popular member of the Ferrari family. More often than not, the big grand tourer is eclipsed by its prettier, sexier and nimbler sisters. Those shopping for a Ferrari are also likely to already have a “family car”. But famous Ferrari tuner hasn’t forgotten the 612, and has released a tuning package for the successor of the 456.

The 5.8-litre V12 engine gets a horsepower bump to 565 bhp from 530 bhp. Torque has increased to 609 Nm from 588 Nm. These new figures are achieved with the help of a “specially calibrated engine management system” along with Novitec’s high performance exhaust system. This means the Scaglietti’s 0 to 100 km/h time is down to just 3.9 seconds and top speed is 325 km/h.

Other additions include a new taillight design and a new tyre/wheel combination – 275/30 ZR 20 up front and 355/25 R 21 rears. Inside, one can customise the seats to their heart’s content. Leather seats can be custom tailored to body measurements and even the addition of lateral support and lowered seat positions for tall drivers can be done. Customers can go as far as choosing the thickness and material of their steering wheel. Like many supercars today, the steering will be flat-bottomed.

DMC Quattro Veloce kit for the Lambo Murcielago LP640.

While we do see Gallardos on our streets from time to time, the Lamborghini Murcielago LP640 is a truly rare sight. But it may not be so unique in Beverly Hills or Monte Carlo, hence the need to dress up the car. For that, Dusseldorf based tuner DMC has come out with a 59,000 euro package called Quattro Veloce.

The QV kit consists of a redesigned spoiler, new hood, side vents and a new “stabilising diffuser”, all made in carbon fibre, of course. Up front, the Murcie gets a new front fascia with redesigned hood and intakes, plus a new splitter.

Inside, a touch of exclusivity is added by the use of ostrich leather whereas ostrich-like cow hide, which is said to be very durable, has been used for the rest of the interior. Add 40,000 euros for the optional leather treatment, carbon fibre seats and diamond forged white carbon wheels. Sounds like every rapper’s dream car.

Power from the 6.5-litre V12 has been increased to 670 bhp (with 660 Nm of torque), which allows the car to move from 0 to 96 km/h (60 mph) in just 3.2 seconds. Acceleration goes on to 343 km/h.

The heart of the beast is kept in a custom red carbon cage for added effect.
