Proper Way of Using Engine Brake...

[Karding]

kinyo, that was the Acura RSX-S. He downshifted by using the power-shift techniques. RSX-S tranny gear ratio is so close that the first people who owns them blew most of their engine and tranny.

nga pala, rev-match is closely associated with heel-toe.

heel-toe, madalas na gamit ng jeepney drivers but they/we/I never knew what its called until the past few years.

[pissword]

oo nga pansin ko sa mga jeepney drivers. and most jeepneys masmataas yung brake pedal kesa sa gas pedal. so mas easier ata gawin yan heel-toe, sinusubukan kong mag engine brake sa mga toll gates hehehe still get the 3K rpm though pero ok lang mukhang masmababa na ngaun, ginagawa ko malau palang tlaga hehehe so medyo bumbagal, and tap tap brakes para alam ng likod na bumabagal ako

I thought engine braking would not use gasoline? Especially on EFIs?

i only use engine braking when going downhill to assist my brakes lalo na kapag may load ang auto ko.
engine braking helps a lot if you know how to perform it well pero kung hindi mastrain lang yung engine,tranny.

[iceman_uel]

may effect sya sa fuel consumption since mataas ang rpm when engine braking.

[kotiko]

But from what I've read those cars equipped with ECUs already have Deceleration Fuel Cutoff, where it stops feeding petrol if you hit a certain RPM while deceleration (which is usually with engine breaking)...

For me I'm trying to use engine braking more when going downhill, dati kasi basta downhill neutral na agad. I think as long as nag-rev matching ka nga, safe naman siya.

Yes, that is true. Using the hand brake from time to time in really long downhill drive would be nice as well.

[alwayz_yummy]

the point is, engine brake mostly pag downhill mo gagamitin, dont ride the clutch, di yan hand tractor...

ang clutch is like a switch-- pag press mo "off" ung power from engine to wheels, "on" pag de-press/release mo...either on- or of lang yan, pag half mo, sigurado yan sira clutch lining mo...

if you wanna learn talaga din ng engine braking, tambay ka sa 4x4ph.. search mo nalang url, di ko matandaan,e..

sa susunod, please, dont imitate drivers na natuto lang...ung nabubuhay sa matandang paniniwala... mas ok kung magread ka, at kung may free driving and track/offroading seminars grab it....

Never do this. It can cause you to spin out.

[Ry_Tower]

another thing i learned is that is going up a hill entails using the 2nd or third gear, better use that gear to do downhill din to support your brakes.

[Ry_Tower]

No, if you use it while in a straight downhill and your speed is already slowed by the engine in low gear and some tapping of the primary brakes. I have done it many times and no problem so far.

Sobrang Fast and Furious movies ata napapanood mo bro ah. Turo yan ng mga 4x4 and offroad experts sa akin. Puwede din kasi uminit ng husto brakes mo kaya sometimes, using the hand brake in tandem with the whole process I first posted above helps. Sorry if I got you confused. Baka akala mo yun lang gagamitin.

There are lots of sound offroading/4X4 techniques that does not translate well to the road. In going downhill, the weight of the car shifts to the front, and with the balance being biased to the front even at rest, you risk making the rear lose grip and become unstable. Add a potential lockup situation and you get the picture.

The techniques your offroading buddies told you is only used when even low range is not low enough. Now, if that's the case, then you probably shouldn't be up there in the first place...

This is what I also have in mind, in our company before they certify us to drive company vehicles they give us seminars and one of those is in "Eco driving". In this seminar, engine braking was also discussed. Its not only during downhill that you can use engine braking actually you can use this technique on your everyday driving to conserved fuel. Please correct me if im wrong.

When driving you can use engine break when you see traffic ahead to gradually slow your car down before it reach near stop without down shifting. Note at this point you don't gas up just wait before you can fully stop in case and that is the time you press your clutch then shift your gear. Correct me again if I'm wrong.

Just one thing moving in my mind, if we use engine break this way will there be any problems we might encounter with our engine or this is just logical.

For more info on this type of engine breaking you can try asking my friend google for more info.

reviving this thread. been an engine braker for a year now. however, i would like to review how you do this yourselves or style/preference.

situation: 60-70 kph downhill zigzag (e.g marcos hiway)
style A: depress clutch and then immediately downshift to 1 gear while clutch is still engaged -> quickly blip throttle to rev-match and immediately release clutch

style B: depress clutch and then quickly blip throttle to rev-match, while clutch is still engaged quickly downshift to 1 gear and quickly release clutch.

right now, i am more accustomed to style A. please post your opinions, comments, and or if there's another/better way of doing it. appreciate it much.

[renzo_d10]

^ Hindi na ako nagrerev-match. Downshift lang.

I don't do it often though, di naman kailangan yun sa usual routes ko.

[ecneret]

question lang, applicable ba ang rev-matching sa pag engine break or pag slow down?

[ash0279]

imho, yes. rev-matching allows the closest/safest possible rpm from the previous high gear.

ah ok. akala ko sa pag-accelerate lang... thanks!

Masyado ka nagbabasa nito ah, halos nakopya mo pa yung reply ng isa.

Use of handbrake on downhill - Australian Land Rover Owners

If the hill is so steep that first low has you going too fast, maybe you shouldn't be there in the first place.

Real life experience is better and the type of vehicle and road is also a factor in using hand brake sometimes during a long downhill descent. Mahirap yung nage-generalize kasi eh (BTW they are talking about LR's in that forum). Tignan mo yung ibang posts dyan, nakatulong din yung hand brake since the normal brakes are starting to fade na due to heat. Just do this on a stright downhill para wala yung potential of a lock-up.
