In the video game Stormworks: Build and Rescue, players can build and pilot a variety of vehicles, including boats, planes, helicopters, and trains. The game features three sizes of diesel engines: small, medium, and large. Large engines are the most powerful, producing 200kW of power, but they also consume the most fuel, with fuel usage increasing exponentially with higher revs (rps). To improve fuel efficiency, players should aim for an rps of around 7-8 for large engines, use gearboxes to keep rps low, and minimize the number of blocks in contact with water to reduce drag. Custom fuel tanks are also recommended for larger boats to ensure sufficient capacity.

Large engines are most fuel-efficient at 7-8 RPS
In the Steam game "Stormworks: Build and Rescue", large engines are most fuel-efficient at 7-8 RPS. This is because the fuel usage of diesel engines is exponential and solely dependent on RPS (Revolutions per Second).
The elastic range of large engines (the RPS range from peak torque to peak power) is 3-18 RPS. It is important to note that diesel engines cannot produce power at 0 RPS and need to be started with electricity. Additionally, they require fuel, air, cooling, and an exhaust to operate.
To achieve the desired speed while maintaining optimal fuel efficiency, it is recommended to use gearboxes to reach 7.5-8 RPS at full throttle. This can be further adjusted by setting the throttle to around 0.9, providing extra power for generators or faster speeds when needed.
The number of cylinders per crank also plays a role in fuel efficiency, with a higher number of cylinders recommended at around 7-8 RPS.
It is worth mentioning that the most fuel-efficient boat setup in Stormworks may differ from real-world scenarios. In the game, the most efficient boat has the least number of blocks below the water when in motion, as the physics simulation does not account for drag in a sophisticated manner.
Overall, keeping the RPS of large engines within the range of 7-8 will result in optimal fuel efficiency, and adjustments can be made using gearboxes and throttle settings.

Custom fuel tanks are better than standard tanks for bigger boats
In the Steam game "Stormworks: Build and Rescue", players can create custom fuel tanks for their boats, planes, and vehicles. While standard tanks are suitable for smaller boats, custom fuel tanks are better for bigger boats for several reasons.
Firstly, custom fuel tanks can be designed to fit the specific size and needs of the boat. In the game, players have reported that custom tanks are more efficient at holding large amounts of fuel, which is crucial for bigger boats with higher fuel consumption. The positioning of the custom tank can also be optimised to improve the boat's stability and floating ability. For example, in boats, having two spaces of air underneath one space of diesel fuel can help with floating and engine placement.
Custom fuel tanks also offer more flexibility in terms of fuel capacity and boat design. Players can designate a good-sized compartment in the hull or fuselage for fuel, ensuring sufficient capacity for their bigger boats. This is in contrast to standard tanks, where fuel capacity may be limited and may not meet the demands of larger vessels.
Additionally, custom fuel tanks can be strategically placed to act as ballast, improving the boat's stability and performance. This is especially beneficial for bigger boats that may require more precise weight distribution.
Furthermore, custom fuel tanks allow players to monitor and optimise fuel efficiency. By tracking fuel usage per second, speed, and litres burned per kilometre, players can make informed decisions to maximise the operative range of their creations.
Overall, custom fuel tanks offer advantages in terms of fuel capacity, boat design, stability, and fuel efficiency, making them a preferable choice for players building bigger boats in "Stormworks: Build and Rescue".

Large engines require fuel, air, cooling, and an exhaust to operate
In Stormworks, diesel engines are the cheapest components that produce power. They come in three variants: small, medium, and large. The small variant produces 20kW and costs $400, the medium variant costs $1000 and produces 60kW, and the large variant costs $3000 and produces 200kW. Diesel engines require more than just fuel to operate, however. They also require air, cooling, and an exhaust. Diesel engines in Stormworks have ports for air, exhaust, fuel, coolant in, and coolant out. Engines will pump the liquids themselves, so there is generally no need for external pumps. However, medium and large engines require pumps on the fuel, air, and exhaust pipes above certain rps values.
The most efficient engine setup in Stormworks, in terms of fuel consumed for power provided, is one running at exactly 8rps. Large engines are most efficient in terms of kW of power per litre of fuel at 7-8rps. At 20rps, one radiator is enough to cool a small engine, two are needed for a medium engine, and three are needed for a large engine. Engines that aren't cooled using seawater have a limit of around 30rps.
In the real world, internal combustion engines require fuel, air, and cooling to operate. They also require an exhaust to expel waste heat from the engine. Air-cooled engines rely on the circulation of air directly over heat dissipation fins or hot areas of the engine to cool them and keep them within operating temperatures. Liquid-cooled engines use a closed circuit carrying liquid coolant through channels in the engine block and cylinder head.

Large engines need more radiators to cool down than small engines
In the Steam game "Stormworks: Build and Rescue", fuel efficiency is a key concern for players. While there is no one-size-fits-all answer to how much fuel is needed for two large engines, players have shared their experiences with fuel consumption in the game. One player with a boat powered by two medium diesel engines reported using 330 litres (87 gallons) of fuel per minute, resulting in a high operational cost.
To improve fuel efficiency, players suggest keeping the RPS (revolutions per second) of the engines as low as possible, with the sweet spot being around 7 to 8 RPS for diesel engines. This can be achieved by using gearboxes or substituting one high-revving engine with multiple low-revving engines. Additionally, the design of the boat also plays a role in fuel efficiency, with boats that have fewer blocks below the waterline being more efficient.
Now, regarding the cooling of large engines, it is indeed true that larger engines require more radiators for adequate cooling compared to smaller engines. Radiators are heat exchangers that play a critical role in cooling internal combustion engines, preventing overheating and potential engine damage. For a small engine running at 20 RPS, one radiator is typically sufficient, while a medium-sized engine may require two radiators, and a large engine may need three. This is because larger engines produce more heat, and a single radiator may not have the capacity to dissipate all the heat, leading to overheating.
To address this, multiple radiators can be chained together to enhance cooling. Additionally, the use of coolant, such as water or oil-based fluids, is crucial in the cooling process. The coolant circulates through the engine, absorbing heat, and then passes through the radiators to release the heat into the atmosphere. This process ensures that the engine maintains an optimal temperature range, improving performance and fuel efficiency while preventing overheating and potential damage.

Large engines are less efficient than small engines in terms of fuel consumption
In the Steam game "Stormworks: Build and Rescue", fuel efficiency is a major concern for players. Some have observed that their creations deplete fuel very quickly, with one user noting that their boat was consuming 330 litres (87 gallons) of fuel per minute, which is described as "absolutely ridiculous".
In the game, diesel engines are the cheapest components for producing power, and they come in three sizes: small, medium, and large. Each size has a different power output and fuel efficiency. Small engines have the highest fuel efficiency at around 10 RPS, while large engines are the most efficient at 7-8 RPS. However, this still means that large engines are less efficient than small engines in terms of fuel consumption, as they require more fuel to produce the same amount of power.
In the real world, the relationship between engine size and fuel efficiency is more complex and depends on various factors. Generally, a larger engine can be more fuel-efficient than a smaller one if it produces the same amount of power while revving less. For example, one person observed that upgrading from a smaller 4-cylinder engine to a larger V8 engine improved their fuel consumption from 18 mpg to 24 mpg. However, if they drove the V8 aggressively, the mpg dropped to 12. Similarly, a Toyota Yaris with a 1.5-litre engine had better fuel consumption and emissions than the previous model with a 1.33-litre engine.
On the other hand, a smaller-engined vehicle can use less fuel than a more powerful counterpart if it takes longer to travel the same distance. Additionally, factors like torque, crank throw, conrod length, number of cylinders, and design of the exhaust system can all affect fuel efficiency.
Therefore, while large engines in Stormworks may be less efficient than small engines in terms of fuel consumption, in the real world, the relationship between engine size and fuel efficiency is more nuanced and depends on a variety of factors, including driving habits and vehicle design.

Frequently asked questions
This depends on several factors, such as the type of vehicle, the speed, and the Revolutions Per Second (RPS). For example, a helicopter with a medium engine uses 5000L of fuel for 1 hour of flying at 100km range, while a plane with a medium engine uses 900L of fuel for the same distance. A boat with 2 large engines, 3 containers, 8rps, and 60 knots may use less fuel.
The most efficient engine setup in terms of fuel consumed for power provided is one running at exactly 8rps. The most efficient boat is one with the least number of blocks below the water when in motion. To improve efficiency, you can also ensure sufficient cooling for the engines, and use gearboxes to keep the RPS of the engines as low as possible.
The fuel throttle is typically set to around 0.4 or 0.5. The air-to-fuel ratio is 14.5 for diesel engines, and 2:1 for modular engines.
