2020 has started with ridiculous heat, a national drought & terrible bushfires in Victoria, New South Wales & parts of South Australia. 

Not a good time to take a holiday in Hawaii..

Due to these events that have just mentioned, here at Mannys Mechanical Repairs, we have decided to lead the charge with implementing emission testing North Brisbane.

This testing will happen on all vehicles when serviced & repaired and on safety certificate inspections.

Vehicle Emission Testing

We have just upgraded on a new Gas Analyser to measure vehicle emissions on Petrol, Diesel, LPG & Natural Gas-

We can supply a print out on the state of your vehicle emissions at idle (sitting in traffic) & at 3000 rpm (cruise modes).

CO: Carbon Monoxide

The combusted dangerous gas that can kill in high concentrations. The lower the reading the better generally we are looking less than .5% with a good catalytic converter this can be down to 0%

HC: Hydrocarbons

is the unburnt fuel- left in the combustion process- This is a major polluter & effects the ozone layer. Hydrocarbons are measured in parts per million (ppm) the lower the better!

Co2: Carbon dioxide

Carbon Dioxide is a result of the combustion process- the higher the percentage the better combustion process which means the engine is running efficiently- still high levels of carbon dioxide cause Green house effect – possible global warming

O2: Oxygen

is measured- excess level of oxygen means there is a possible exhaust leakage which can effect emission readings or a engine fault. Though the gas analyser is a balance system- if there is a abnormal reading it will show irregular readings on the other settings.

NOx: Nitrogen oxide

This one is the bad one- a mixture of nitrogen & oxygen added with fuel hydrocarbons(Diesel)  Nox is released under extreme combustion heat- To combat this manufactures add a EGR- Exhaust gas recirculation system to cool & lower NOx .

 NOx gases causes Acid rain & Asthma.

Lambda & Air/Fuel Ratio

The ideal air/fuel Ratio for petrol is 14.7:1, Diesels can range from 14.5 :1 to  20 :1 That is 20 air molecules to 1 fuel molecule. lambda is a nominated reading by the engine software calibrator but generally a lambda of 1 is 14.7 :1 reference

Emission Testing North Brisbane

By reading the above, you can be assured we take our work seriously.

Global Warming is serious stuff and we can do our part to ensure vehicles are properly serviced, tuned & keep the polluters off the road.

 Manny`s Mechanical Repairs is leading the way!

Today`s car engine has come a long way with the advent of computerized fuel injection, but the operation principals are virtually the same since the early model t ford.

The car engine requires several components groups that supply spark & electrical, fuel distribution & engine compression. These groups must be in sync with each other to obtain engine combustion and power.

The term “Tune” can be related to a musical instrument like a guitar or a violin, occasionally the chords have to be adjusted on the instrument to give the right clear note. Hence tune up!.

But in a car engine , The term tune is the optimum combustion of air, fuel & spark coming together referred to as ‘Stoichiometric’ 14.7:1 which is 14.7 parts of oxygen molecules to 1 fuel molecule this combination gives ultimate combustion resulting in power and low emissions-this is the holy grail.

Back in the old days pre-1986, cars were brought to the garage, ignition points, spark plugs replaced ,engine timing set and the carburettor was adjusted- the car was Tuned & off you went home to watch Hey Hey its Saturday. The only problem was that these components fitted to the vehicle would wear with in a relative short time and the car would start to have poor fuel economy and be OUT OF TUNE.

UNBURNT FUEL OR EXCESS HYDROCARBONS IS ONE OF THE BIGGEST DETERIMENT / POLLUTERS TO THE ENVIROMENT AND THAT WITH THE OLD AIR CONDITION GAS FREON 12 CAUSED DAMAGE TO THE OZONE LAYER.

By the year 2000 nearly all vehicles had computer engine management systems, the carburettor was phased out because it could not deliver a accurate supply increments of fuel unlike today`s electronic fuel injector. Today`s car computer or engine management system.. controls, fuel delivery, spark, it adjusts engine timing to suit load conditions and can control engine valve duration and to make things more scarier .., it even controls the throttle opening and has dispensed with the old accelerator cable , YOUR VEHICLE`S ENGINE IS VIRTUALLY CONTROLLED BY THE COMPUTER. The engine management system has a feed back sensor which monitors oxygen in the exhaust emissions-this information feeds back to the computer telling it to modify fuel injector spray pulse durations and constantly keeps the engine close to a Stoichiometric state at most times-this is called a closed loop system.

IN OTHER WORDS THESE ENGINE MANAGEMENT SYSTEMS TUNE THEMSELVES AND CAN ACTUALLY LEARN !

But.., like everything else in life, components fail and deteriorate ..actuators like fuel injectors get blocked, idle motors seize causing a high idle, manifold gaskets perish causing

air leaks affecting idle, ignition coil drivers can fail causing engine miss, oxygen sensors can slow down causing high fuel consumption.

Ironically even in the computer/information age we live in now the car engine still requires constant repair and vigilance with a trained mechanic to ensure all components are running true and minimal emissions are produced this is what a tune up is all about.
