Bosch makes a version of almost everything under a modern car’s hood. Wiper blades are just the one thing the consumer sees.

Thanks to providing an optimal fuel/air mixture, deposits on the inlet valves of gasoline direct-injection engines have been largely minimized.

michaelovitch holy cow! Bosch actually answered you! well kind of.... I made it to 60000 miles and only now do I need a valve servicing. I suggest the ol' Italian tune up every once in a while, and if your in the U.S. look for Top Tier gas. After I get my valves cleaned I'll add a catch can. Hopefully that'll help

H bit motoring u

correct. I think they call this job creation

well said.its the fact

im pretty sure once direct injectors will become more common in the near future, the cost will go down unless u go under dealership instead of regular auto shop or diy. plus more aftermarket direct injector parts become more common to buy too since direct injector seems more efficient other than diesel engine.

***** That's optimistic but sadly untrue. The overhaul of the system in labour cost alone is a huge debt, that won't go down, wages keep rising.

we shall see. direct injectors has been around since the early 1900s so its not like its something new. but its has been close to perfected in the last decade or so. i mean direct injectors will have it's place among diesel, flex fuel, bio diesel, regularly gasoline engine. the cost will have to go down if there's going to be mass production of direct injectors for years to come. who knows. otherwise why build direct injectors in the first place if it's so expansive. it's place in common newer model cars over older engines. so we don't really know what the future holds on direct injectors.

This is design to make the car last less and buy new

If they installed oil catch cans on the crankcase ventilation and educated people on how to maintain them you would have a lot less buildup on the intake valves

Catalytic failure

TheVintagetamiya as well as the emissions of soot and nox, which is something that was never associated with gasoline cars (since the 90's at least) and is why they're all required to have regenerative particulate filters in Europe since late 2018… which decreases their reliability even further

@@arnemaeschaelck5012 Well, my Audi A3 exhaust pipe is all black...

richard cero it would be a great car

ahh okay.

Salvo Farina FIAT (actually Alfa Romeo) were the first to use common rail injection on Diesel engines. Mitsubishi were the first to use the modern direct injection on petrol engines.

only a brand is for what they entered but not for what they don't know.

The right answer to this question is cars are expensive to manufacture and have a small profit margin, vehicle technology on the other hand, is much easier to manufacture and is a field growing faster than automotive production. In short, building cars = expensive and need a huge expensive plant, building/designing car technology can be done with a couple bright engineers and a computer with Autocad.

Why can not cease air valve and replace spark plug by diesel injections system but for fuel and air

port injection goes into the intake at some point, over the valves and into the cylinder. direct injection goes directly into cylinder.

Shreyas Jagtap For optimum combustion, the injected fuel mass must be regulated in a certain ratio to the air mass supplied (air mass : mass of fuel = 14.7 : 1). With the hot-film air mass meter the air mass flowing into the intake manifold is determined. Via the throttle valve the for the required torque necessary air mass for the combustion is set. The engine control unit determines the optimum fuel mass to be injected through the injectors into the combustion chamber from the air mass and the residual oxygen content of the exhaust gas (oxygen sensor).

+azthundercloud The Fuel-supply system is designed with two fuel filters. A pre-filter in the tank protects the in-tank fuel pump during the whole vehicle lifetime. The second filter is a fine-filter between fuel-pump and injection system. This fine-filter is placed either in-tank or in the fuel line between tank and engine. If in-tank then it is designed for lifetime and no change is needed. If outside the tank then it depends on the vehicle manufacturers mandatory service or change intervals. The entire system design and mandatory service intervals reliably protects the fuel injectors from impurities regardless of the user’s fueling behavior. Modifications are neither required nor advisable.

A 1.4 turbo drives better than an N/A 1.8, because of the added torque. Also Toyota petrol engines with Atkinson cycle have GPFs (Gasoline particulate filter), like in their hybrids to get the lowest CO2 and NOx levels they can.

maybach300c The HFM measures the air mass in the air intake tract. The sensor element consists of a heated sensor membrane over which the intake air flows.

+Doc. Volt The main difference between a gasoline and a diesel engine is the combustion process - especially the pressure level. For that reason there are different concepts of the injectors.

+Yogi Anmaris No, because the systems are completely different. Indirect injection injects into the port fuel, direct injection injects side or center mounted directly into the cylinder head. Each direct injection engine needs a defined spray design for each system requirement, engine, and combustion strategy.

+danekeeper1 Optimized air flow in the cylinder and improved jet flow of the laser-drilled high-pressure injectors result in clean combustion in the DI engine. This minimizes the build-up of deposition products on the engine valves caused by back-flowing exhaust gas.

@@boschmobility it's not about the backflow of exhaust, it's the PCV oil vapors, and EGR soot that's introduced into the engine which gets the intake valves dirty really quickly

Gasoline Means petrol, most probably for SI System

+Xgamer121X A correspondingly high pressure is required in order to achieve fine atomization under all conditions and thus ensure a good fuel/air mixture formation. It is a fundamental requirement for complete and clean combustion.

+rick9021090210 The durability of a gasoline injector is 15 years/240.000 km

Austin Ogland Yes, exactly. Have a look at out website, where you can find more detailed information about the function of our gasoline direct injection: products.bosch-mobility-solutions.com/en/de/powertrain/powertrain_systems_for_passenger_cars_1/direct_gasoline_injection/direct_gasoline_injection_23.html

***** Unfortunately we can not comment on future developments from Bosch. Please be assured that we include all technical solutions for powerful, economical and clean mobility in our development process.

In Brazil, Bosch does not offer any systems in which alcohol is injected into the manifold and flex fuel directly into the combustion chamber in combination.

John Kerns With Scavenging the intake and exhaust valves are briefly opened simultaneously. This creates a dynamic flow between the intake and exhaust sides of the engine, purges rest gas out of the combustion chamber and increases mass flow in exhaust-gas turbocharger. The increased exhaust gas mass flow and better cylinder charging generates a higher torque at low engine speeds, which counteracts the turbo lag.

John Kerns I believe the answer is because there is turbo pressure at the intake valves

Thanks for your question but we're not able to make any statement about this. Therefore, please directly contact the respective manufacturer. Thanks.

Bosch Mobility Solutions Global I really liked the part where it says: mso-tstyle-rowband

If you know the software then please tell me too.....
