What causes a car to start consuming fuel excessively – car talk (1) – nigeria electricity for refrigeration heating and air conditioning 9th edition pdf

Here’s my issue. I just bought a honda accord 2008 4cyl and i noticed that fuel consumption is alot higher than my previous 03. It guzzles alot fuel. Each time i accelerate it makes a loud roar like and open air intake, the kind of sound you hear in race cars with turbo chargers. The dealer said it is due to the pimped up exhaust. But i don’t hear the sound from the rear but from around the dashboard and below. I also noticed that the air intake pipe that is supposed to run from the front grill on top of the radiator to the air filter is missing. My mech said its a missing catalyst but i suspect it has sometime to do with the missing pipe and the loud roar. Ps i hate noisy cars. Oh and when i accelerate on highways i can literally see the fuel needle drop.

The roar around the dash area could well be an exhaust leak, that should be checked. The Accord being FWD has a flexi pipe linking the exhaust mid-section to the front, covered with braided steel (in most cases). Make sure the flexi section (corrugated steel) has no cracks.

The air intake pipe from the lower section of the airbox to the grille is your cold intake. If it’s missing, your engine will be drawing in hot air from the engine bay. Cold air is denser, and allows a more complete fuel burn. It CAN affect gas mileage adversely. I would get it replaced, then re-assess gas consumption.

I would suggest an OBD scan, your ’03 Honda Accord is fully OBD II compliant. All the items marked with an asterisk will normally trigger an engine check light (CEL). It would help too, if you can recall when you noticed the higher than normal fuel consumption. Did it occur after any work was carried out on the car? The thermostat is an area I would look into – if it’s stuck open (or it’s been removed) the engine will never reach its optimum operating temperature. The CTS will sense the engine is not hot, and the ECU will send more fuel through the injectors as a result. This is done by altering the duty cycle (the amount of time the injectors are held open will be longer).

Tyre pressures are also important, if the pressures are too low, the rolling resistance will place more load on the transmission, then the engine will work harder. The same goes for brakes that are binding (sticking on).@Siena:U r right bt take a look at lifespan of d engine.Has d engine bn changed b4?If nt,that’s may b d cause N 3.0L engive is a V6 engine.Let mi advise u d steps to take.(1)service d fuel line(injector nozzles,suction filter,replace spark plugs(check.
