Traditionally buses use a diesel engine in South Korea. But when our government became conscientious about the environment, authorities forced bus companies to switch over to LNG buses. But the problem with the LNG bus is the distance. Natural gas based bus can’t go a long distance. This is a big issue in Seoul city where we expect heavy traffics at all times (not just limited to rush hours.) So they couldn’t convert all buses to LNG.
With this said, most buses in the city are still diesel engine based. They are extremely fuel efficient. But the problem is again with pollution from carbon waste. Carbon sludge buildup happens more often when a bus has to make a frequent stop due to city heavy traffic.
Jeju Island (the southern end of S.Korea) is dedicated to making a clean environment. So they began to get rid of conventional diesel engine based buses. Instead, they started using full electric buses. This sounds like a great idea. But what happens if a bus needs to charge when passengers are on the bus? Do they need to wait more than half an hour?
They resolved this issue by changing batteries at the bus station.
In other words, just like your mobile phone, you can change a bus battery on the go. This takes a few minutes but a definitely viable solution. Jeju Island declared that they will make the Island carbon free place eventually. If this works at one place, why can’t we duplicate it in other places such as Seoul city?
Unfortunately, people living in the city is not so patient. They can’t wait for a few minutes stop for a battery replacement. So we’re stuck with carbon monster, diesel engine buses for a while until we find alternative solutions.
Luckily there is a solution available. If you prevent carbon sludge from building in the intake manifold area with a diesel engine bus, you get a very clean(environmentally friendly) bus.
This is a car inspection report.
In the exhaust emission test, the result says it’s “0.0%” emission. At first, the inspector got suspicious of the result. So he ran tests over and over again. The results were all the same. This is what happens when you install D Clean. Since D Clean will remove carbon waste in real time, there is no carbon sludge buildup. This preserves a diesel car clean (zero pollutant gas emission).
