The Wartsila 46 Engine is one of the most widely used power plant engines developed by Wartsila for large-scale electricity generation. The Wartsila 46 engine platform has been installed in many power plants around the world, providing reliable and efficient power generation for utilities, industrial facilities, and independent power producers.
Several versions of the engine have been developed for power plant applications, including:
Wartsila 46
Wartsila 46B
Wartsila 46C
Wartsila 46F
Wartsila 46DF (Dual Fuel)
These engines are typically installed as part of large power plant generator sets, where multiple engines operate together with alternators to generate electricity for national grids or industrial power systems.
Many modern gas power plants, diesel power plants, and heavy fuel oil power plants use Wartsila 46 engines as the primary power generation equipment for electricity production.
On IndustrialMarinePower, companies can list Wartsila 46 power plant engines, generator sets, and spare parts for sale or wanted, including surplus power generation equipment from operating or decommissioned power plants.
Wartsila 46 engines are designed for large power generation projects and typically produce electricity in the megawatt (MW) range.
Typical output depending on engine configuration:
| Engine Model | Power Output |
|---|---|
| 6L46 | approx. 5 – 6 MW |
| 8L46 | approx. 7 – 8 MW |
| 9L46 | approx. 8 – 9 MW |
| 12V46 | approx. 10 – 12 MW |
| 16V46 | approx. 14 – 17 MW |
| 18V46 | approx. 16 – 19 MW |
Large power plants may operate multiple Wartsila 46 generator sets, allowing total plant capacity to reach 50 MW, 100 MW, or even higher depending on the installation.
The Wartsila 46DF version is designed for dual-fuel power plant operation.
Dual fuel technology allows the engine to run on:
Natural gas
Marine diesel oil (MDO)
Heavy fuel oil (HFO)
This flexibility allows power plant operators to switch between fuels depending on fuel availability, operating costs, and environmental regulations.
Wartsila 46DF engines are widely used in gas-fired power plants and LNG-based electricity generation facilities.
Wartsila 46 engines operate as part of complete power plant generator systems, and several major components are required for installation, maintenance, and overhaul.
Typical power generation equipment and spare parts include:
generator / alternator units
turbochargers
fuel injection systems
gas admission systems (for DF engines)
cylinder heads
pistons and piston rings
cylinder liners
crankshaft assemblies
lube oil pumps
cooling water pumps
engine control and automation systems
exhaust gas systems
power plant auxiliary equipment
These parts are frequently traded for power plant maintenance, spare parts supply, and engine overhaul projects.
