ก็ไปเจอบทความตัวนี้

Abstract
The effect of ozone addition to the intake air on combustion in compression ignition engines was examined using a Diesel CFR engine. The experimental results show that ozone addition improves the combustion characteristics. Addition of 500 ppm ozone, for example, increases cetane number by 2 to 4 and lowers the compression ratio of the ignition limit by 1 to 2, depending upon the kind of fuel used and the operating conditions. Regarding exhaust emissions, a small decrease in CO, hydrocarbons, and particulates and a small increase in NOx have been observed with ozone addition under the fixed operation condition.

สรุปให้นะครับ เค้าก็บอกว่า ถ้าใส่ 500 ppm ozone ก็จะช่วยเพิ่มค่า ซีเทน (ในน้ำมันดีเซล) ประมาณ 2-4 แล้ว ลดค่า compression ratio (อัตราการอัด) ประมาณ 1-2
ขึ้นกับ ชนิดน้ำมันและสภาวะแวดล้อม ลดค่าCO ได้"เล็กน้อย"
ก็โอเคครับ ส่วนบทความการทดลองจริงๆ ผมไม่มีตังค์ไปซื้อบทความของเค้าได้ครับ
34 usd กว่า ๆ (เป็นงานวิจัยของ nissan diesel ครับ)
ก็แล้วแต่วิจารณญานของท่านแล้วกันครับ
เพิ่มค่าซีเทน ก็ประมาณ รถเบนซิน ใช้ 91 กับ 95
แต่ผมจะแปะ บทความนี้ให้ท่านอ่านเองแล้วกันครับ ไม่อยากแปล อิอิ

Abstract
References
The mixture gas composed of hydrocarbon compounds and air/O2 exposed to discharge was analysed by FTIR.
The emission spectroscopy of combustion in the enriched condition of O2 and O3 was not very different because it was assumed that the consumption of O atoms required for combustion was consistent. The spectrum around 1750 cm-1 of the mixture gas, which did not appear before discharge, was detected by FTIR. The generation rate of the by-product around 1750 cm-1 strongly relates with O3 concentration. It was suggested that O3 is the major molecule reacting with vaporised hydrocarbon compounds. A candidate for the by-product was supposed to be C8H16O or/and C8H16O2 from the reference absorption spectra of FTIR. The by-product was produced with thin O3 concentration, which was 0.62 g/m3 in the test, although O3 was emitted as extra when injected O3 was more than approximately 2 g/m3.
