World Environment Day: How preventive maintenance can help with sustainability

To celebrate the date, Niterra shares the importance of maintaining the review plan, in order to reduce the levels of gas emissions

São Paulo, June 2023 - A Niterra, Japanese multinational owner of the NGK and NTK brands and specialist in components for ignition systems, take advantage of World Environment Day, comemorado em 5 de junho, to reflect how the actions of the automotive sector carried out in the present will impact the future of humanity. The main one is the practice of preventive maintenance that ensures the reduction of the levels of gas emissions by the vehicle. Lack of revision can cause components to break down, increase levels of fuel consumption and gas emissions.

"Keeping the maintenance plan up to date ensures the perfect functioning of the vehicle and the maintenance of the emission levels established by regulatory standards", comments Hiromori Mori, Technical Assistance Consultant at Niterra do Brasil. Thinking about how to help society in reducing the levels of emissions from motor vehicles, Niterra indicates the continuous observation of the irregular behavior of the vehicle, difficulty in the match, failures and increased fuel consumption. For Mori, The vehicle must be taken for an inspection, determine what is occurring and arrange for the repair of the automobile as soon as possible, ensuring optimal emission levels.

Main components and systems of vehicles requiring special attention

In addition to the maintenance of the injection system, Perfect operation of the ignition system must be ensured. Even if the fuel is injected correctly (fuel mass and fan shape), The ignition system ensures the correct burning of the combustible air mixture. Within this system can be highlighted the following components:

 ;

• Spark plug: responsible for generating the spark that will burn the air/fuel mixture. If failures occur, the mixture will not be properly burned leading to increased fuel consumption and gas emissions.
• ignition cables: conducts electric current from the coils to the spark plugs. Cable problems can cause motor failures and reduced firing efficiency.
• ignition coils: transform low voltage (12 a 14 volts) at a high voltage (25.000 a 35.000 volts). This elevation allows the generation of the spark in the spark plug.

As for the injection system, Among others, two important items stand out::

 ;

• Oxygen sensor (lambda probe): component measures the amount of oxygen in the exhaust gases, allows the system to evaluate how the fuel injection was and makes it possible to adjust it.05
• Sensor MAP: This is a fundamental sensor for the correct functioning of the injection system. It is through the information provided by it that the mass of air entering the engine is calculated (Speed Density System), enabling the determination of the correct mass of fuel that will be applied.

"The great challenge of the present day is to know the maintenance plan of each specific vehicle. To make our lives easier, Most automakers have on their websites the vehicle manual and tables with the scheduled maintenance for each automobile.", Mori explains. "Some also offer the closed-price review services, which allows the customer to evaluate maintenance plans and overhaul costs".
