Extreme Combustion Engine

The Extreme Combustion Engine (ECE) is an IV tier multiblock for generating power from combustible fuels. The ECE is a direct upgrade from the Large Combustion Engine because it can output more than 5x the power. However, the ECE must be supplied with 8,000 L/h of lubricant to run, and optionally 40 L/s of liquid oxygen to boost the machine. Boosting is highly recommended because it triples the maximum power output and increases the fuel efficiency from 100% to 150%. Power is extracted from a 4A dynamo hatch on the back of the machine. Do not exceed the maximum EU/t of the dynamo hatch or else it explodes. Save on fuel by automatically toggling the ECE with an RS latch connected to a Lapotronic Supercapacitor. The ECE is superseded by the Universal Chemical Fuel Engine which has no cap on the amount of power it can produce.

The ECE has no tiered components. The maintenance hatch and muffler hatch may replace any robust tungstensteel machine casing that is NOT touching a gear box casing. The input hatch(es) may replace any tungstensteel turbine casing that IS touching a gear box casing. A quadruple input hatch is recommended l for inserting all the necessary fluids. The dynamo hatch is limited to the center casing on the right side of the structure, opposite the controller, and cannot be greater than 4A. Use the Multiblock Structure Hologram Projector to visualize/build the structure.

Wallsharing

ECEs may wallshare each of their sides to save on casings and frame boxes. That does NOT include the input hatch due to the restriction on its location.

The ECE generates power from a limited number of combustible diesel fuels. The following table lists the available options and their densities (EU/L). The most popular options are Jet Fuel A and high octane gasoline. Both are typically used in the Universal Chemical Fuel Engine too.

The ECE has two operating modes, listed below. The machine automatically switches between them based on the available inputs. Boosting is highly recommended because it triples the maximum EU/t and increases the fuel efficiency from 100% to 150%. The liquid oxygen is not difficult to sustain--simply build a dedicated Vacuum Freezer or Planetary Gas Siphon.

Default

• Inputs: Fuel + 8,000 L/h lubricant
• Output: Maximum 10,900 EU/t at 100% fuel efficiency

Boosted

• Inputs: Fuel + 8,000 L/h lubricant + 40 L/s liquid oxygen
• Output: Maximum 32,700 EU/t at 150% fuel efficiency

The ECE also has its own efficiency value that is directly proportional to the power output of the machine. The efficiency of the ECE increases linearly while the machine is active and almost immediately resets back to 0% while the machine is idle. It takes 25s (default) or 75s (boosted) to reach maximum efficiency. This means the ECE should run for as long as possible but not forever because additional EU is voided once the dynamo hatch is full. View the current efficiency by using a Portable Scanner on the controller, or by looking at the efficiency value in WAILA.

Power is extracted from a 4A dynamo hatch on the right side of the structure. Do not exceed the maximum EU/t of the dynamo hatch, or else the ECE will explode. Breaking the dynamo hatch or exceeding the total EU is perfectly safe; the ECE will not explode if an attached battery buffer or Lapotronic Supercapacitor (LSC) is full and there is nowhere for the EU to go. Any additional EU is simply voided. It is highly recommended to automatically toggle the ECE with a redstone RS latch to avoid wasting fuel--see the LSC page for a guide on setting that up.
