Adjusting Fuel Mixture: My Summer Car Guide

To change the fuel mixture in My Summer Car, you need to adjust the air-fuel ratio. This can be done by locating and adjusting the mixture screw in the carburettor. It is recommended to check the parts catalogue and order the fuel and airflow meter before making any adjustments. Players should also ensure that the engine is warm and that the choke is pushed all the way in before adjusting the mixture screw. The ideal air-fuel ratio is around 14-16, and players can use a fuel mixture gauge to accurately monitor the ratio.

The fuel mixture screw is located in the middle of the carburettor when viewed from the front

To change the fuel mixture in My Summer Car, you'll need to adjust the fuel mixture screw on the carburettor. This can be found in the middle of the carburettor when viewed from the front, with no other screws near it.

Before making adjustments, it's recommended to check the parts magazine and order the fuel and airflow meter. You'll also need a screwdriver to make the adjustments.

To get the ideal air-fuel ratio of 14-16, you should first rev the Satsuma until the temperature gauge is at its halfway point. Then, adjust the screw until the numbers displayed on the fuel mixture gauge are around 14. You can also adjust the idle mixture without the gauge by taking off the hood and driving the car to the highway. Adjust the screw until the car reaches speeds of 160km/h or more.

It's important to ensure that the engine is warm when making adjustments and that the choke is pushed all the way in. A warm engine will have an AFR of around 12 on a cold start, then rise as it heats up. You can also use the choke to lower the AFR on a cold engine for better performance and faster heat-up.

The engine should be warm when making adjustments to the fuel mixture

When adjusting the fuel mixture in My Summer Car, it is important to ensure that the engine is warm. This is because, without the correct air-to-fuel mixture, the car can sputter or stall. A warm engine ensures that the fuel mixture gauge provides an accurate reading, enabling you to make the necessary adjustments.

To achieve this, rev the engine until the temperature gauge reaches its halfway point. This indicates that the engine has warmed up to a stable idle temperature, allowing for accurate adjustments to the fuel mixture. It is recommended to push the choke in during this process, as pulling it out reduces the air-fuel ratio.

Additionally, warming up the engine can help with the choke, as it temporarily enhances air intake, producing a richer mixture. This can make it easier to adjust the fuel mixture and prevent the car from stalling.

By following these steps and ensuring a warm engine, you can make precise adjustments to the fuel mixture, optimizing the performance of your car in My Summer Car.

It is worth noting that, while warming up the engine is necessary for accurate adjustments, idling for extended periods can be harmful. Excessive idling can strain the engine and affect various components, such as the emissions system, cylinders, and spark plugs. Therefore, it is advisable to warm up the engine just enough to reach the stable idle temperature required for fuel mixture adjustments.

Pushing the choke all the way in will increase the air-fuel ratio

To change the fuel mixture in My Summer Car, you will need to adjust the air-fuel ratio. This can be done by locating and adjusting the mixture screw in the carburettor.

Before making any adjustments, it is recommended to check the parts magazine and order the fuel and airflow meter, as well as ensuring you have a screwdriver. Once you have the necessary parts and tools, you can proceed with the adjustments.

To locate the mixture screw, look at the carburettor from the front; the screw should be in the middle, with no other screws nearby. It is important to ensure that the engine is warm before making any adjustments.

Now, pushing the choke all the way in will increase the air-fuel ratio. This is because the choke controls the air-fuel ratio in the engine, playing a crucial role in fuel enrichment. When closed, the choke restricts airflow, resulting in a higher vacuum, which causes the engine to draw in more fuel. This creates a richer air-fuel mixture, allowing the engine to warm up faster and run smoothly.

By pushing the choke all the way in, you are essentially reducing the choke's effect. This means that the airflow will not be restricted as much, leading to a higher proportion of air in the air-fuel mixture. This is particularly important when adjusting the mixture screw to achieve the ideal ratio.

It is worth noting that the fuel mixture gauge, also known as the AFR gauge, can be a helpful tool in this process. This gauge displays the air-fuel ratio of the installed carburettor while the engine is running. It is most accurate when the engine has warmed up to a stable idle temperature, which is indicated by the halfway mark on the temperature gauge.

In summary, pushing the choke all the way in will increase the air-fuel ratio by reducing the choke's effect and allowing for more airflow. This, combined with adjustments to the mixture screw, will help you achieve the desired air-fuel ratio for optimal engine performance in My Summer Car.

The ideal air-fuel ratio is 14-16

To change the fuel mixture in My Summer Car, you'll need to adjust the air-fuel ratio. This can be done by locating the mixture screw in the carburettor and using a screwdriver to adjust it. The ideal air-fuel ratio is 14-16, which can be monitored through the fuel mixture gauge (AFR gauge) purchased from the parts catalogue. This gauge is attached to the left-hand side of the dashboard.

To achieve the ideal ratio, it is recommended to first warm up the engine to its stable idle temperature, which is indicated by the halfway mark on the temperature gauge. Once the engine is warmed up, you can adjust the mixture screw until the gauge displays a reading between 14 and 16. Make sure the choke is pushed all the way in during this process, as having it pulled out will reduce the air-fuel ratio.

It's important to note that the specific ratio within the 14-16 range may vary depending on your personal preferences and driving conditions. Some players have reported that a ratio of 14.7, which is the Stoichiometric A/R ratio for petrol, provides the most power. Others have found that a slightly richer mixture, around 13.8 to 14, yields better performance. Ultimately, you may need to experiment with different ratios within the ideal range to find the sweet spot for your car.

Additionally, it's worth mentioning that the gear ratio and driving conditions can also impact the optimal air-fuel ratio. For example, if you're rallying and running the engine hot, you might want to tune the ratio lower. On the other hand, if you're drag racing and the engine is at idle temperatures, a higher ratio may be more suitable.

The fuel mixture gauge can be purchased from the parts catalogue for 549 mk

The fuel mixture gauge, also referred to as the AFR gauge, is an essential component for adjusting the fuel-air ratio in My Summer Car. This gauge can be conveniently purchased from the parts catalogue for 549 mk. It is a valuable tool that displays the air-fuel ratio of the currently installed carburettor while the engine is running.

To install the fuel mixture gauge, simply attach it to the left-hand side of the dashboard without any bolts. It is important to note that the gauge must be wired to function correctly. The accuracy of the gauge is also dependent on the engine temperature; for the most precise readings, ensure that the engine has warmed up to a stable idle temperature, indicated by the halfway mark on the temperature gauge on the dashboard.

Once the gauge is installed and the engine is warmed up, you can begin adjusting the fuel-air mixture. This is done by using a screwdriver to adjust the mixture screw located in the middle of the carburettor when viewed from the front. It is important to ensure that the choke is pushed all the way in during this process.

By following these steps and making adjustments, you can optimise the fuel-air mixture for better engine performance in My Summer Car.
