The FAA approved the water pour procedure for piston engines in aircraft. The water would steam up and the carbon would loosen and go out the exhaust. Yes the steam would hit backside of those intake valves.

A faulty O2 sensor is tied for first among the most common reasons a car’s check-engine light goes on, and is responsible for 5.81% of the repairs. The typical cost of replacing the sensor has risen 2.5% year over year.

The brand has added safety features, improved the comfort and convenience levels across the board, and made more changes than meet the eye.

My dad, on cold winter drives, would partially block the radiator on our old family car with a piece of cardboard, because the cooling system wouldn’t get hot enough for the thermostat to open.

Thinking about parallels for GDI engines, it is known that higher pressures (than the current level of 200-350 bar) will reduce PN significantly. I recall having seen results for up to 1000 bar in the literature. Eventually, we will also see diminishing gains in trade-offs also for GDI engines as pressures increase. I would not rule out that we could get up to around 1000 bar in the far future, but I cannot see any rationale in a level approaching 3000 bar in this case. Anyhow, it would be unknown territory and several issues could be expected that, in contrast, seems manageable with diesel fuel in the near future. As in the diesel case, one should also realize that the "fix" of using GPF must also be considered. As with DPF, we could have a technology here that will reduce PM/PN to very low levels under any driving conditions. So, why bother with pushing injection pressures to even higher levels (i.e. over 500 bar), or using double injection systems (IDI and DI), if you can have a "fit and forget" solution as GPF? GPFs are not expensive. For sure, GPFs also have some issues but I cannot see much future in doing whatever you can to avoid GPFs. Note that filters (DPF & GPF) will also trap ash, metals and other particles than those that originate from fuel combustion. Some of these particles are very potent and pose health hazards, so they need to be filtered out in any case. But, talking about Delphi and this specific article, for sure, we will see other injection equipment suppliers who will also offer something in the range of 500 bar.

In an attempt to boost the sales of its double aisle 777 commercial aircraft, Boeing Co (NYSE:BA) recently announced that it was looking to increase the seating capacity by reducing the size of the lavatories. Company officials said that they would be able to add up to 14 extra seats […]

To complete the new 500+ bar system, Delphi Technologies has developed all system components including Multec 16 injectors, pumps, forged rail as well as the appropriate engine control system and software. These components, which further improve durability and reliability, also require no or only minor physical changes to existing engines because they match existing packaging constraints and interfaces. The 500+ bar system could be used in production from 2022 onwards.

Reducing the number of exhaust gas particulates, including those smaller than 23 nm, will help manufacturers meet increasingly stringent future global emissions standards.

Furthermore, the years considered for the study are as follows: Historical year – 2014-2018 Base year – 2019 Forecast period – 2019 to 2025

I still don’t think that in terms of absolute numbers of cars/issues that this is on the scale of the things that the domestic manufacturers deal with, but maybe Honda just isn’t used to dealing with this volume of issues and dealers+corporate need to adjust to accommodate this sad new reality.

Earlier this year I watched most of the trial that concerned the child abuse that took place at Children’s Theater.   I read the verdict as…
