Shortcomings of current process
1. Activated carbon adsorption
2. Direct combustion
3. Catalytic oxidation
4. Ozone oxidation
1. Inconsistent efficiency
Efficiency sharply drops when it works for long time.
It happens as nutrients for microorganisms are insufficient.
2. Unequal growth of microorganisms
Efficiency decreases, hard to handle when factors change suddenly

1-3. 최적 압축비 이상으로 증가할 때 오히려 크랭크 축으로 전달되는 torque가 감소하는 이유 ?
압축비를 증가시킴으로써 엔진의 효율을 상승시킬 수 있다. 그러나 압축비를 무한정 높이지 못하는 원인들이 있는데 가솔린 엔진에서 압축비 제한의 가장 주요한 요인은 knocking이다.

- Yes, it was something to that effect...
Do you recall what that additive was?
Yes, as a matter of fact, now that
you bring it up, the additive was

Noisy!
It was the worst explosion in the histo
combustion engine that uses both conventional fuel and electric motor. Electric cars only use the electricity stored in the battery. Although these alternatives cannot compete with the efficiency of the current gasoline cars due to technological constraints, our group believes that electric cars will substitute gasoline cars in the future. Hybrid cars will bridge gasoline cars and electric cars a
efficiency. Hybrid cars run on battery power at low speeds and switch to traditional internal-combustion at higher speeds. Since the capability of a secondary battery is not enough to replace the existing engine, it still needs to have both battery-powered motor and engine to generate enough power.

이때 비열비 는 공기에 대해 1.4 정도로 일정하다. 따라서 열효율은 압축비만의 함수이며, 압축비가 증가함에 따라 기관의 열효율도 증가한다.
기관 열효율의 증가는 bsfc(brake specific fuel consumption)의 감소를 의미하여 단위 거리를 달릴 때 배출하는 전체적
