More air getting into the engine improves the combustion, reducing the soot amount. It does help while driving thru high lands too, due to the intake pressure increasing.
Formspring doesn't feed Blogger anymore but I've felt should share this. In a simple way, GO TURBO!!!

Gone fishing some bangus, now heading to Palawan island. 1st xperience sa smartphone, might buy one to ease contacts walang offshore.

Toyota: bring Diesel Corolla back to the Philippines
10 years ago, when the first Corolla Altis was released, it had the 2C Diesel engine phased out. Meanwhile, in many other markets there are still Diesels available for the Corolla. In Europe, the D4-D series with direct injection, turbocharging and intercooler made its way, while the old 2C prechamber, naturally-aspirated and full-mechanical design remained on less emissions-enforced countries. Currently, in India the Corolla is fitted with the 1.4 D4-D while in Pakistan the 2C is still the only Diesel available. In the Philippines, the D4-D can be perceived as expensive, thus unattractive, while the 2C is still beloved by many owners and commercial operators. There are still many customers who would consider to get a new Corolla if there was still Diesel engine available. No wonder I've seen Hyundai i30 and Ford Focus in considerable numbers.

Direct or Indirect: different injection setups, each one with its own advantages
The adaptability of the Diesel cycle to some alternative fuels like biodiesel , pure vegetable oils (either straight or waste) and ethanol is already known, but due to specific characteristics of each fuel, different fuel injection systems are most suitable for each application.
Indirect injection, more used in older engines, usually has higher combustion temperatures, which are better to handle a vegetable oil due to the amount of glycerin, that is harder to burn completely and thus taken away from biodiesel. Prechamber design also has lower injection pressures, what leads a cheaper hardware to have a satisfactory performance. In the Philippines, it basically remains on the market in older models such as the Mitsubishi L300, Hyundai H100 and Nissan Urvan Escapade.
Direct injection requires higher pressures to get a proper combustion because of the lower temperatures demanding a smaller contact surface between the fuel and the hot compressed air inside the combustion chambers. An advantage from this setup, by the other side, is a reduction in NOx emissions, what Diesels are hardly blamed for.
Ang kaya sa pagbagay ng diesel cycle sa ilang mga alternatibo fuels katulad biodiesel, purong langis ng gulayin (alinman diretsong o basurang) at ethanol na tinatawag, ngunit dahil tukoy na mga katangian sa bawat gasolina, magkakaibang mga sistema ng gasolina iniksyon ay karamihan-naaangkop para sa bawat application.
Indirekta iniksyon, mas ginamit sa mga lumang engine, kadalasan ay may mas mataas na temperatura ng pagkasunogna mga mas mabuting upang pangasiwaan ang sa isang gulay langis angkop sa ang dami ng gliserin, na mahirap sumilab sa kumpleto at kaya dadalhin ang palayo sa biodiesel. Prechamber disenyo din ay may mas mababang pressures iniksyon, kung anong humahantong ng mas mura hardware na magkaroon ng maimis pagganap. Sa Pilipinas, nanatiling talaga nito sa merkado sa mas lumang mga modelo tulad ng Mitsubishi L300, Hyundai H100 at Nissan Urvan Escapade.
Direct iniksyon ay nangangailangan ng mas mataas pressures makakuha ng maayos pagkasunog dahilan sa ang mas mababa mga temperatura demanding isang mas maliliit na balat ng contact pagitan ng gasolina at ang hot compressed air sa loob pagkasunog kamara. Ang isang bentahe sa setup na ito, pamamagitan ng iba pang mga panig, ay isang pagbaba NOx emissions, ano ang Diesels ay para bagang blamed sa mga.

new project in mind, retrofit a Diesel engine in a light motorcycle
I have some interests in motorcycles for a long time, and after a recent trip to China last month this has grown um on me stronger. I'm seriously considering to buy a motorcycle, but for budget reasons it must be a compact one, in a displacement range no bigger than 400cc.
Actually, after a few sucessful Diesel engine retrofits into some Honda VT600C, Yamaha Virago, Suzuki M800 and even into a Harley-Davidson Sportster, now I want my own Diesel motorcycle. Altough I'm currently very busy to focus on this personal project, might be starting it in a few months.
