Amount of greenhouse gases produce by cars5 answersCars are a significant contributor to greenhouse gas emissions, particularly carbon dioxide (CO2). When a gallon of gasoline is burned in a car's engine, it produces approximately 24 pounds of greenhouse gases, with over 19 pounds released directly from the car's tailpipe as heat-trapping pollutants. On average, gasoline-powered vehicles have a fuel efficiency of 22 miles per gallon and produce about 8,887 grams of carbon dioxide for every gallon of fuel used. The emissions can vary depending on factors such as the type of gasoline used, the vehicle's fuel efficiency, and the distance traveled in a year. The automotive industry also contributes to greenhouse gas emissions through the energy-intensive manufacturing process, with a typical vehicle requiring approximately 120 Giga Joules of energy input. By using clean energies such as solar PV, wind, and fuel cells in automotive manufacturing, the greenhouse gas emissions can be reduced.
How to make an emission gases measumerement in vehicles?5 answersTo measure emission gases in vehicles, there are several methods and devices available. One approach is to use gas sensors such as mq2 and mq7 to sense the constituents of exhaust gases, which can be displayed on a smartphone for detailed monitoring. Another method involves the use of a vehicle-mounted emission test system, which collects nitrogen and oxygen measurement results from a sensor and estimates the emission measurement result of the full vehicle based on the sensor data and pre-obtained measurement difference. Additionally, there are vehicle emission prediction systems that calculate instantaneous and accumulated emission data using empirical databases, vehicle parameters, and real-time correction coefficients. These methods and devices provide ways to measure and monitor emissions from vehicles, helping to control and reduce harmful pollutants in the environment.
How is the full lifecycle co2 emission of electric vehicles?3 answersThe full lifecycle CO2 emissions of electric vehicles vary depending on factors such as the type of fossil fuel being replaced, the weight of the electric vehicle, and the source of electricity used for charging. Replacing petrol fossil fuel cars with lighter electric cars has the greatest potential for reducing CO2 emissions. The ratio of embedded to in-use CO2 emissions has doubled in the last 30 years for conventional vehicles, and is several times higher for battery electric vehicles. However, even with the variability in environmental impact assessment, electric vehicles are found to be less carbon-intensive in their lifecycle compared to diesel or petrol vehicles. The optimization potential for reducing CO2 emissions through renewable energy-oriented charging patterns is found to be rather small, and achieving the potential of electric vehicles to solve environmental issues requires optimizing driving and charging patterns as well as reducing the carbon intensity in the electricity grid. Electric vehicles have the potential to reduce CO2 emissions, but further measures are needed for maximum environmental benefits.

What are the current market penetration rates of energy-efficient vehicles (EEVs) and battery electric vehicles (BEVs) in Malaysia?
6 answers
The market penetration rates of energy-efficient vehicles (EEVs) and battery electric vehicles (BEVs) in Malaysia reflect the country's evolving automotive landscape, influenced by environmental concerns, government policies, and consumer attitudes. As of the data available, EEVs hold a modest share in the Malaysian automotive industry, with only 3 percent of the market share, indicating a low level of acceptance and purchase among Malaysian consumers. This low penetration rate underscores the challenges EEVs face in gaining widespread acceptance despite their environmental benefits and the government's efforts to promote cleaner transportation options. Battery electric vehicles (BEVs), a subset of EEVs, are also experiencing a gradual increase in interest and adoption in Malaysia. The adoption rate of electric vehicles (EVs), which includes BEVs, was less than 1% in 2018. However, with the government's ambitious plans and policies, such as the National Energy Policy (NEP) aiming for zero carbon emissions by 2050 and the Low Carbon Nation Aspiration 2040, the adoption rate is anticipated to rise significantly to 38% by 2040. This projected growth is supported by initiatives to address the challenges of EV adoption, including the development of infrastructure like charging stations and battery swapping stations (BSS), which are crucial for overcoming range anxiety and encouraging the shift from internal combustion engine vehicles to EVs. Despite these optimistic projections and initiatives, the current market penetration rates of EEVs and BEVs in Malaysia remain relatively low, hindered by various factors such as consumer attitudes, cost considerations, and the availability of charging infrastructure.
