Achieving Better Fuel Economy

by : Miranda Restelle

To keep up with the existent emission and fuel efficiency laws, Mazda rides are now run by fuel injected engines. To beat more strict requirements, Mazda fuel injector works with a the engine control unit (ECU) to deliver accurate mount of fuel that is to be processed for combustion yielding more power and less fuel wastage. As an electronically controlled valve, the part is supplied with pressurized fuel via the fuel pump. It can actually open and close many times in a second. To operate the injector, it needs to be energized to move the plunger that opens the valve. An electromagnetic device is responsible in controlling and regulating pressure build-up which the injector needs to squirt out fuel through a tiny nozzle. The nozzle atomizes the fuel making it easily burnt as fine mists. The ECU is responsible in calculating the amount of fuel which is to be released via the fuel injector. As the injector is mounted in the intake manifold, they spray fuel directly at the intake valves which are connected to specific sensors that feed inputs to the ECU to arrive with accurate calculations.

Fuel injection is a mechanism that aims to supply engine with accurate amounts of fuel when sustaining smooth operations. Its efficient service significantly reduces fuel wastage and emission levels in yielding excellent air-fuel ratio. Operational benefits to having engine's equipped with fuel injections system are smoother and more dependable engine response even on quick throttle transitions, more dependable engine starting, lesser effects of extreme ambient temperatures, reduced maintenance intervals, and increased fuel efficiency. Fuel injection systems started when carburetors were replaced with throttle body fuel injection systems. The system works with electronically controlled fuel injector valves as bolt-on replacement for the carburetor. Gradually, the system evolved into a multi-port fuel injection system. The system now has fuel injector for each cylinder to spray fuel right at the intake valve. This modern injection system provides more accurate fuel metering that achieves better fuel economy. With substantial increases to horsepower and torque, engines with modern fuel injection system acquire better responses with powerful performance.

Your plays crucial roles in the functionality and service of fuel injections systems. As the actual part that injects the fuel through the manifold, it needs to be kept in good working conditions to maintain system precision. Injector failure is often caused by the intrusion of contaminants that speed up corrosion and wear rates. At wider range of operating temperature, faultiness and damaged also come inevitably with age. If you already suspect damages to the injector, immediately perform diagnostics to follow it up with timely adjustment or repairs. When you decide to replace your stock Mazda fuel injector, consult a qualified service technician to arrive with excellent results to system maintenance. To select the right injector replacement, you need to make sure that the size and application specifications of the replacement match the original. Normally, naturally aspirated engine will have B.S.F.C. of .50 which means the engine uses .50 lbs. of fuel per hour for each generated horsepower. Turbocharged engine uses .60 lbs or more of fuel per hour. Most injectors could max out an 80-percent duty cycle which is an industry standard.
