Which type of engine replaced steam engines in fire fighting beginning in 1907?

The transition to internal combustion engines in firefighting beginning in 1907 marked a significant advancement in firefighting technology. Internal combustion engines provided several advantages over steam engines, including increased efficiency, reduced operational time, and improved mobility. The internal combustion engine allows for quicker start-up times and doesn’t require the extensive preparation and maintenance needed for steam engines, such as building up steam pressure.

Moreover, the compact nature of internal combustion engines made firefighting vehicles lighter and more maneuverable. This allowed firefighters to respond to emergencies much faster and with greater accessibility compared to steam-powered engines, which were typically larger and less mobile.

This shift to internal combustion engines ultimately paved the way for modern firefighting vehicles, which utilize more advanced engine technologies today. The other options like electric engines, hydraulic engines, and diesel engines represent different types of propulsion systems, but it was the internal combustion engine that specifically began to dominate the firefighting scene around that time.
