Lasalle cars were some of the most iconic vehicles of the early 20th century. They were known for their sleek designs and dual ignition, which made them some of the first cars to use spark plugs. What you may not know is that Lasalle actually had a patent on this technology. Dual ignition allowed the engine to run more smoothly and produce more power, making these cars some of the most advanced of their time.
What is Dual Ignition?
Dual ignition is a type of engine where the fuel and air mixture is ignited simultaneously by the spark plugs. This was first patented in 1885 by Émile Laffite and Joseph Robin. Dual ignition engines are generally more efficient than single-ignition engines because they use less fuel to produce the same amount of power. Additionally, dual ignition engines create less produces carbon emissions than single-ignition engines.
How Dual Ignition Worked in Lasalle Cars
Dual ignition was a feature found on some late-model Lasalle cars. Dual ignition worked by having two sets of plugs, one for the regular fuel and one for the premium fuel. The dual ignition system allowed drivers to use either type of fuel without having to change the plugs.
Why Dual Ignition Was Removed from Lasalle Cars
Dual ignition was removed from most Lasalle cars in the early 1950s due to reliability and performance issues. Dual ignition had been a feature on earlier Lasalle models, but it caused more problems than it solved. Dual ignition made it difficult to start the car in cold weather, because the engine would not turn over as easily. It also made it difficult to shift gears, because the engine would stay in one gear during acceleration and braking. Dual ignition also caused more gas consumption, because the engine had to work twice as hard to produce the same amount of power.
Conclusion
Dual ignition is a system that was first used in 1892 by the French manufacturer, Lasalle. It is a type of engine with two sets of spark plugs, one for each cylinder. This system allows the engine to run more smoothly and efficiently because it prevents knock, or the knocking sound that often occurs when two compression engines are running at different speeds.
