Emission Testing North Brisbane

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!

What is Timing Belt?

Have you ever wondered what a Timing Belt is? 

Engine breathing & more important air flow is the heart & soul of good performance of a internal combustion engine.

How a Timing Belt works

I have selected 3 pictures to try to capture the job of a timing belt. The quintessential word here is “TIME”.

A brief run down:

In a nutshell the engine is a air pump with a piston moving up & down. The down speed of the piston causes a negative pressure (vacuum) and air enters the chamber via a intake valve (this can be through one or two valves) –  Induction Stroke.

The intake valve closes at a precise time, when the piston moves up it compresses the air & injected fuel (compression stroke) and the spark plug fires, causing a combustion process resulting in a flame front & high pressure. The combustion pressure forces the piston down at a precise time sending torque down the crankshaft turning linear force into rotating torque (power stroke).

As the pistons ends the downward travel, the exhaust valve opens at a precise time. The piston then moves back up pushing exhaust gases out the exhaust valve (exhaust stroke).

Why Do I have to Replace the Timing Belt

Timing is the issue & it has to be precise. To open & close valves at the precise time in relation to piston position, this requires a timing belt. These timing belts are due to be replaced approximately every ten years or at 60 000km – 100 000km. Some makes have different time intervals, so please refer to your repair manual for the exact times.

Stretched timing belts can throw the whole series of engine stroke events totally out of sync with the valve events, resulting in poor performance, poor fuel economy even possible engine failure!

Why so expensive to replace?

Replacing timing belts should also incorporate replacing the water pump. Some vehicles may require the engine to be removed from the car to replace the timing belt.

Many manufactures require special holding and locking tools to hold engine components in the exact position to install the belts. This can be very expensive just to get the right tools to do the job.

What is a Timing Belt?

Manny`s Mechanical repairs specialises in engine Tuning & excellent fuel economy, replacing timing belts, water pumps & timing chains. We ensure your vehicle is up to date & have the equipment to measure good fuel economy & power. Replacing timing belts is critical & should not be avoided costing can be around $1000.00 including labour(approx.), but that is better than losing your engine due to hubris or neglect.

I hope this has helped.

Knowledge is power- Power is organized effort!

Car Services

Cars are complex- make no mistake about it.

Electrics, computers, can-bus communication and all other necessities, there is a protocol which technicians have to follow- unfortunately the general public has no idea what is required so here is a attempt to demystify the whole process of servicing.

What is in a Car Service?

A service can be broken into three categories

  1. Parts
  2. Consumables
  3. Labour

Labour

  • basic general service for a car only

car services

The vehicle is checked over for damage & scratches before test drive-test drive incorporates, listening for knocks, squeaks, rattles, driving braking shuddering. a full electronic check- load test battery @150-200 amps & monitor load performance, light check, interior lights power windows, perform full electronic computer scan-with report, check fuel trims.- under bonnet, check drive belts, check for any leaks (coolant or oil) check brake fluid & coolant concentrations, check radiator& cooling system, top up all levels.

Jack up car (HALF WAY) – check steering and suspension (shock absorbers, ball joints)  remove wheels check tyres-note condition, rotate tyres-check tyre pressures. Check brakes- include brake hoses , adjust brakes & hand brake.

Fully jack car up – drain oil, replace oil filter, check gear box & differential oil levels, inspect & report exhaust damage, engine & transmission mounts, check for lower suspension wear (IF ANY)-Check drive shafts(for torn boots or cv damage),tail shafts, grease if applicable. check for any structural damage or rust.

Lower car – fill with correct fresh oil- check air filter- replace if necessary, start vehicle-check for leaks-test drive.

Time is about 1- 1.5 hours price approx $120- $189.

Parts

If your car has a turbo (Diesel or Petrol) only full synthetic oil will be used.

Oil prices can range between $60- $120 –depending on make/model.

  • Oil filter approx $18-$38
  • Air filter approx $22.00- $80.00
  • Fuel filter approx $35-$145
  • Spark plugs range from general plug $8.00 each to $55+ each ( may take 8 plugs

Consumables

  • Wiper blades  $12- $66.00 each
  • Coolant $15.00 a litre
  • Brake fluid $22.00 a litre

Car Services

I have bared my soul when it comes to servicing prices my opposition will of course undercut me because that is business- A word of warning-beware of cheap service prices-gimmicks or gurus when you use a booking agency-you are sending money overseas(THEY TAKE 30% OF THE BOOKING FEE).., to finish  a small 4 cylinder car which is constantly serviced average price is around $250 – $300. Diesel 4wd can be around the $450 + diesel parts can be expensive-but i strongly recommend a diesel fuel filter with every service
