Maintenance Tips for Diesel and Petrol Vehicles

 

Car Yoga consists of 1. Green Motoring which is explained here, 2. Vehicle Fuel Saving explained under Energy Saving of Conservation Home and 3. Transport Simplicity described in Simple Home. The vehicle which you own whether it be a car, a motor cycle or a truck helps you to go from one place to another. You must ensure that it also helps the environment. Rather, make sure it does not harm the environment. Hence you must practice Car Yoga (or Motor Cycle Yoga).

The five Car Yoga cardinal Principles are as follows

  1. It is maintained well
  2. It causes less air pollution
  3. It does not cause noise pollution
  4. It is fuel efficient
  5. It is used only when it is absolutely necessary

The burning of fossil fuels and often their incomplete combustion in engines, leads to the release of a number of polluting gases such as carbon monoxide, carbon dioxide, nitrogen oxides, oxides of sulphur, hydrocarbons into the atmosphere. These gases have serious ill effects on human health, vegetation, materials, climate etc.

Other reasons for increasing vehicular pollution are outdated automotive technologies and traffic management systems, the age of vehicles, and the poor road conditions. Vehicular pollution can be reduced by minimizing use of personal vehicles and instead using the efficient public transport. The use of unleaded petrol also helps in the reduction of lead pollution. Using alternative fuels such as compressed natural gas (CNG), battery operated vehicles instead of petrol or diesel vehicles, helps in reducing pollution. Maintaining vehicles in good condition can also contribute towards this.

Petrol Vehicles

  • Adjust and clean the spark plug periodically.
  • Clean the air filter and oil filter regularly.
  • Tune the engine by adjusting correct air to fuel ratio.
  • Clean carbon deposit from the silencer.
  • Maintain the correct tyre pressure.
  • Shifts gear correctly.
  • Mix recommended quantity of oil into petrol if required.
  • Carryout maintenance as recommended by the manufacturer periodically.
  • Avoid breakdown maintenance.
  • Get a valid Pollution Under Control Certificate from the authorized centre.
  • Avoid congested roads and rush hours.
  • Start a car pool to reduce the traffic on the road.
  • Stop the engine if you are stuck in one spot for more than 2 minutes.
  • Drive at optimum speed/recommended speed of 30 – 40 kmph for two wheelers and 45 -55 kmph for four wheelers.
  • Lower the fuel consumption per km run, lower the pollutant emitted in to the atmosphere.

Diesel Vehicles

  • Clean oil filter and fuel filter regularly.
  • Keep the engine well tuned by setting idling speed and tappet clearance of valves.
  • Clean the fuel injectors and set the fuel pumps according to the manufacturer’s recommendation.
  • Check the tyre pressure regularly
  • Clean the carbon deposit in the cylinder.
  • Avoid use of clutch pedal as foot rest.
  • Check free rotation of wheels.
  • Drive with optimum speed of 40 kmph.
  • Get a valid PUC Certificate from authorized testing pollu_carcentre.

Petrol Vehicle - Pollution Norms
If you own a vehicle, you must have its exhaust pollution checked once in six months and a certificate from the authority must be obtained evidencing that the exhaust emitted from your vehicle is within the limits. If you fail, you will be fined Rs. 500/- and even your vehicle may be seized.

Carbon monoxide content- Permissible level

  • Carbon monoxide content for Petrol vehicle from 0.1% to 0.8% is considered very well. 

  • As per government norms for a new vehicle up to one year, the Carbon monoxide content can be up to 3%.  If the vehicle is more than a year old the permissible limit is 4.5%.

  • Then you need to take steps to reduce the carbon monoxide content by overhauling the engine and replacing some parts. Though you spend money initially, eventually you will gain monetarily as your vehicle will have better mileage. Controlling carbon monoxide in your vehicular emission is good for both your health and vehicle’s health. 

Diesel Vehicle

  • Permissible limit of smoke density (Diesel) is Hartridge Smoke Unit (HSU) 60 and for non-urban areas (HSU) 70.

  • The children should insist that they will get in to the vehicle only if the vehicle has the latest pollution PASS certificate.

  • There are schools that refuse to allow cars to enter their campus which don’t have the pollution PASS certificate.

Vehicular Noise

  1. Similarly the cars should neither use a pipe horn nor a vacuum horn. Instead they must use mild and original horns which come with the vehicle.

  2. The next is the noise pollution caused by the audio systems in the vehicle like Radio and CD / Tape player.

  3. The third and the most important source of noise pollution in a vehicle is the one from its exhaust. If the level of Carbon monoxide is more, the exhaust will create more noise. The noise could also be due to some damage or cracks prevalent in the exhaust.

Important
Start your car after opening the garage door and allowing a couple of minutes to pass.  This is to safe guard you as the garage could be full of carbon monoxide. This has caused death and must be taken seriously.

Emission Norms

Petrol Driven Vehicles
2/3 Wheelers – Carbon monoxide - 4.5 % V/V
Four Wheelers CO - 3.0 % V/V
Four Wheelers 5 Years old or 80,000 km done – CO - 4.5% V/V

Diesel driven vehicles
Smoke - 65 Haritridge Unit.
